Prevents Heartworm Disease

So, what is heartworm disease? And why is heartworm prevention so important? Essentially, if you don't prevents heartworm disease, the intestinal parasites can cause significant organ failure if it's not treated and managed right away. It starts out as an infection caused by a parasitic worm that enters your pet's system.

Known as the Dirofilaria immitis, this parasitic worm enters your dog's body by way of a mosquito's bite. Dirofilaria immitis worms are intestinal parasites, meaning they require a host to feed off of, which is your dog in the case of canine heartworm disease. An existing heartworm infection can very easily transform into full fledged heartworm disease if it is not treated properly.

Is Trifexis bad for your dog?

The debate about Trifexis spinosad milbemycin oxime is still ongoing. Some claim that it's a bad medication for dogs, while others say the benefits of this drug outweigh any risks involved with taking it.

Trifexis Dosage for Dogs

The argument over whether or not to administer Trifexis - an oral tablet used for certain parasite prevention in cats and dogs- has been hotly debated by veterinarians across America and beyond since its release on December 2nd 2013 as part of a multiyear agreement between Elanco Animal Healthand MSD Animal Healthcare Company LLC (Merck & Co., Inc.). The agreed upon terms include "promotion exclusively through veterinary channels," something which was disputed because animal vets don't typically handle retail pet pharmacies like CVS/pharmacy Pet Care RX or

Trifexis dog dosages include:

  • 140mg/2.3mg for dogs 5lbs to 10lbs
  • 270mg/4.5mg for dogs 10.1lbs to 20lbs
  • 560mg/9.3mg for dogs 20.1lbs to 40lbs
  • 810mg/13.5mg for dogs 40.1lbs to 60lbs
  • 1620mg/27mg for dogs 60.1lbs to 120lbs


This dosage continues upward, depending on the weight of the dog. If you're unsure what dose to give your dog, make sure to discuss it with your vet and they'll surely be able to ensure you're providing the right amount.

Trifexis Overdose Symptoms

To make sure your dog is as safe as possible, it's good to know all of the symptoms that might represent an overdose.

Typically, you'll be able to tell how your dog is handling the medication within about an hour of giving it. Keep an eye out for signs that might show your dog is confused, or otherwise behaving abnormally.

Other symptoms of an overdose can include large amounts of vomiting, lethargy, or exhaustion.

These can be signs of a larger problem, so it's a good idea to contact your vet if you notice these symptoms.

Is Trifexis Safe For Pregnant Dogs?

Your best bet to know whether Trifexis spinosad milbemycin oxime is safe for pregnant dogs, and specifically your dog, is to consult with your vet. If your pet has a pre-existing condition, it’s especially important to check in.

Side Effects of Trifexis for Dogs and Cats

Keep in mind that if you give your dog Trifexis while pregnant, the side effects from this medication are similar to that of canine morning sickness. A common side effect of the medication is vomiting and feeling lethargic. It's often likely that vomiting occurs as well.

Because vomiting is also common in pregnant dogs, along with seeming lethargic, it can be hard to determine whether your pooch’s sickness is coming from the medication or from pregnancy. If your pet starts vomiting after using Trifexis, visit the vet to be safe.

Trifexis For Cats

While there is no variety of the Trifexis brand that is made for cats, the medication that is used within the brand can be used for them.

What that means is that the active ingredient is safe for cats and dogs. However, please talk to your vet before using Trifexis on your cat to see if they can provide a better option. Trifexis as a brand is made for use on only dogs.

Trifexis For Puppies

Trifexis treats and controls adult whipworm infections and also prevents heartworm disease at the same time. Since Trifexis controls adult hookworn and works to ensure heartworm prevention for adult hookworm, it's not the best medicine to treat whipworm infections, ensure heartworm prevention, kill fleas, prevents flea infestations, and handles intestinal parasites for young puppies.

However, Trifexis is safe for puppies who are at least 8 weeks old, and who weigh at least 5lbs. Intestinal parasites, prevent flea infestations, adult hookworm, heart worm, heartworm disease, whipworm infections, adult roundworm, adult hookworm roundworm, heart worms, and hookworm roundworm and whipworm infections are treatable with Trifexis. At the same time, always consult a vet.

If you're seeking to provide this medication to a puppy lighter or younger than those limits, it's best to talk to your vet about the reasons why so that they can provide the best course of action. Otherwise, permanent negative effects can result.

Instead, a vet will be likely to have other options that can help your puppy. There is certainly another medication that can kill fleas and prevents flea infestations in a safer way than Trifexis kills fleas and prevents heartworm disease.

How Does Trifexis Work?

Trifexis uses a combination of two medications: milbemycin oxime and spinosad. The Trifexis medication can be taken as a chewable tablet or a pill. Depending on what your dog's vet thinks is best, you might be able to choose between the two options.

You can expect to give a Trifexis chewable tablet or two separate pills for a while. If your dog only receives one or two monthly doses of Trifexis, then the Trifexis monthly doses won't be as effective. Monthly doses of Trifexis chewable tablet or pills need to remain consistent in order to effectively control adult hookworm and prevents flea infestations.

After your pet is tested for an existing heartworm infection, your dog can start taking FDA approved doses of the Trifexis chewable tablet or in pill form. The only thing left is when you are at the vets office, make sure to mention if your dog is breeding if your vet isn't already aware. Trifexis can be dangerous for breeding males and breeding females alike.

Breeding females and breeding males are at a greater risk for developing heartworm disease. When looking at heartworm disease in breeding males and breeding females, heartworm preventives and treatment options should be paused until puppies are born and weaned.

After the puppies are more self sufficient and don't rely on their mom for food, breeding females can be treated for heartworm disease. The treatment of heartworm disease should be put on pause for breeding males as well, unless immediate intervention is necessary. Adult whipworm and heartworm prevention is the best approach for dealing with complete heartworm prevention prior to it becoming heartworm disease.

If you can catch complete heartworm prevention prior to heartworm disease, your dog will thank you! It all starts with looking into medication that not only treats and controls adult heartworm disease but also prevents heartworm in general. At the same time, you'll want to pay close attention to complete safety information before seeking prescription approval for dog Trifexis.

Trifexis Benefits For Dogs

Compared to something like a flea collar, Trifexis for dogs gets more coverage. Furthermore, there is less of a worry about the kinds of poisoning that can occur with flea collars.

Some other benefits can include:

  • Can begin working in just 30 minutes
  • Vet recommended
  • Easy to use
  • Treats and prevents fleas, heartworms, and more
  • Tablets are chewable
  • Simple to give at home
  • You can limit the amount of pills needed

Does My Dog Need Trifexis?

When wondering if your two dogs needs FDA approved doses of Trifexis chewable tablets, think about your pet's situation and if there are other alternatives that can provide complete heartworm prevention prior to any of the side effects of Trifexis. While the Trifexis brand may not be necessary, some kind of flea, tick, and worm preventative is a good idea. These medications essentially help to keep your dog healthy and happy, and assists with keeping the parasites they can attract out of your home.

This is hugely beneficial to both pets and their owners, especially because some of those intestinal parasites can bring along added illnesses or other passengers. Trifexis is an amazing method that prevents flea infestations and kills fleas and prevents heartworm disease for your fur babies. Trifexis controls adult hookworm roundworm and whipworm infections in such an impressive way and it is shown to be a helpful flea treatment for dogs with adult roundworm.

Trifexis Most Common Adverse Reactions Reported

Most medications that we give our pets can contain some side effects. Typically, one of the most common adverse reactions reported of Trifexis that can occur in dogs is vomiting. That said, this doesn't tend to be a long-lasting or damaging side effect, but more one of brief discomfort.

Most common adverse reactions may include:

  • Decreased appetite
  • Diarrhea
  • Skin or ear redness
  • Itchiness
  • Lethargy 
  • Vomiting occurs
  • Triggers pre existing epilepsy

Pre existing epilepsy is a risk factor for dogs that are prescribed Trifexis. The medication needs to be used with caution when administered to dogs with pre existing epilepsy. There's still a lot to learn about the impact of Trifexis and pre existing epilepsy because not much is known about Trifexis and how it impacts dogs that are high risk for other medical conditions.

Another one of the most common adverse reactions reported of Trifexis is the flavor. The pill form of Trifexis can be very unfavorable for your pets. It's been reported that vomiting occurs in a new dog that doesn't like the flavor of the pill. A secret tip is to feed your dog peanut butter along with their monthly doses of Trifexis.

Luckily, Trifexis can also be purchased as a beef flavored tablet. Instead of bad-tasting pills, the beef-flavored table is a lot easier for pets to consume and the beef flavored tablet is less likely to upset your pet's stomach because it has a good taste. As long as your dog weights five pounds and is at least eight weeks old, then this beef flavored tablet of Trifexis works to protect your pet from future parasite infections.

A decreased appetite can also result if your dog hates the flavor of the pills as well. From there, vomiting occurs and it becomes a major mess. Try to seek out the beef flavored tablet wherever possible for this reason as well. Dogs will be much more open to a beef flavored tablet than an unflavored pill, so a beef flavored tablet is the way to go.

Monthly doses of Trifexis medication can cause decreased appetite in your family pet, which can lead to serious adverse reactions over time especially if your pet's weight loss lasts for too long. Even when you have prescription approval for FDA approved doses of Trifexis chewable tablets or beef flavored tablet, flea medicine can cause serious long-term adverse reactions like chronic dehydration or hunger. Let Trifexis protect your dog in a flavorful way with a beef flavored tablet.

Dogs who have epilepsy should not use this medication, as the adverse reactions can be severe and result in problems that become permanent. Some dogs might have an MDR-1 mutation in their genes, causing them to be sensitive to avermectin and increasing the severity of adverse reactions to Trifexis.

If this is true for your dog, it's best to avoid using this medication. If you're unsure, it can be a good idea to get a DNA test done for your dog before you give them Trifexis because the serious adverse reactions can be fatal. Furthermore, it's worth knowing the symptoms of Trifexis poisoning for dogs with this mutation.

If you're wondering how long Trifexis side effects last, then it's worth keeping in mind that they shouldn't last too long or be in excessive amounts.

If the issue is going on for hours after the pet has been given the medication, it might be worth a call to the vet.

Types Of Flea Medication For Dogs

There are many types of flea medicines out there for dogs, but some are better than others. Four of the most common options that provide complete heartworm prevention are Sentinel, Revolution, Trifexis, and Bravecto.

Before we dive into the medications that provide complete heartworm prevention for dogs, it's important to mention that they all require a prescription and must be administered on a monthly basis. However, none of them address tapeworms, so keep that in mind.

If you want to help your dog become heartworm free, consider these medications and consult with your vet on the best heartworm preventive for your dog. As always, make sure you thoroughly understand the complete safety information.

Complete safety information can be found on the labels of these medications. The timeline of your dog's last exposure to fleas is important to mention as well. Your dog's last exposure will have an effect on the efficacy of flea medication for dogs, so try to be as accurate about the last exposure date as possible. If your pet's last exposure was to a single flea or multiple fleas, it doesn't matter.

What matters is whether or not at least one flea was able to lay eggs in your dog's fur. The date of the last exposure to fleas will inform your dog's vet about the best medication that kills fleas and prevents nasty fleas from being able to lay eggs in your dog's coat ever again. So, just be sure to mention the date of last exposure for these reasons and many others.


To begin with, Sentinel for dogs is able to prevent hookworm roundworm and whipworm infections, but not tapeworms. It also only kills adult fleas, but not larvae or eggs. In addition, it isn't known to prevent other parasites like ticks. Normal doses of Sentinel are also safe for nursing, breeding or pregnant dogs. It can also be used on puppies as young as 4 weeks old, and over two pounds. Furthermore, it comes in tablet form, like Trifexis for dogs.


Revolution is used topically and only prevents roundworms in cats. The same is true for hookworms. It does not take care of whipworms. Revolution is also capable of killing both kill adult fleas and their eggs. One aspect that sets Revolution apart is that it is made to prevent other parasites, such as ticks. In addition, it is safe for pregnant, breeding or nursing dogs. Puppies must be at least 6 weeks old.


Trifexis kills fleas and prevents hookworms, roundworms, and whipworms. It also stands apart by being able to kill fleas at all stages of life. Furthermore, it doesn't kill off other parasites. Trifexis, for ticks, isn't going to work well.

If you're looking to use it on a breeding, nursing or pregnant dog, it's best to talk to a vet first. Puppies must also be at least 8 weeks old and 5lbs to use.


Another popular option is Bravecto, which is very similar to Trifexis. Bravecto is able to kill off fleas as well as ticks on top of providing protection from heartworm. However, it does not prevent intestinal parasites, while Trifexis is able to do just that.

Revolution vs Trifexis

Some of the key differences between Trifexis and Revolution are that Trifexis is able to prevent more types of worms in dogs than Revolution does. Furthermore, Trifexis is a capsule, while Revolution requires topical administration on dogs.

Finally, Trifexis kills all stages of flea life while Revolution only kills off adults and eggs.

What is comparable to Trifexis for dogs?

Which is better Trifexis or Nexgard?

Trifexis or Nexgard... That is the question. It's a daunting task to decide which medication for flea and tick prevention you will use on your four-legged friend. Trifexis has been around longer than its competitor Nexgard but some people might prefer it because of this (or not). Others may enjoy using modern medications like Nexguard more so they can be sure their pet stays up-to-date with what studies show are newer developments in medicine today. Is one better? It really depends on personal preference!

Trifexis Reviews

When you're shopping for a product to use on your pet, it's a great idea to take a look at what other users are saying about it. After looking through several reviews, we can help you to determine whether or not this medication is going to be best on your pet.

Here are some notes on what customers have had to say:

  • Dogs may not always enjoy the taste
  • Not all dogs will be fond of the smell
  • It's convenient that it's only needed once a month, and it tends to work quickly and at a fantastic price
  • Some customers can find that it's a bit expensive for their liking.

The good news is that while not everyone loves the price, it appears to work well and offer plenty of value for the cost.

Trifexis Cost

Keep in mind that the Trifexis price for dogs can be somewhat costly, and it does require the prescription of a veterinarian.

However, because it is prescribed by vets, there is a much higher chance that it will be safe for your dog, whereas a number of issues, some very serious, can occur if you aim for a lower-cost medication. You can also compare prices through a number of places that handle pet prescriptions.

Where To Buy Trifexis

Because the Trifexis flea pill is a medication that you need a prescription for, options for purchasing it can be fewer than over-the-counter flea meds.

Unfortunately, that means that you cannot buy Trifexis at Amazon, but you can get Trifexis at Costco as well as a few other places including: - $75-$95

KV Supply – About $85

1-800-PetMeds – About $100

Keep in mind that these prices can depend on the weight of your pet as well as the number of treatments you opt for.

Things like Revolution for cats are also not found at Amazon.

Essentially, any pet medication that requires a prescription won't be available through that particular site, but there are a few that cater specifically to pet prescriptions, such as those listed above.

Trifexis Without Vet Prescription

This medication cannot be purchased legally without a vet prescription, so if you run into a site that claims to provide it without need for a vet, be very wary because it may not be the right product and may cause harm to your pet.

This is also true if you find Trifexis cheaply when compared to the standard pricing. While a lower cost can be tempting, the resulting product can also be very dangerous.

Trifexis Online

One of the conveniences that has come along in recent years is the ability to purchase prescription medications like Trifexis for sale through websites like Chewy and 1800PetMeds. However, keep in mind that you will need proof of the prescription to order Trifexis online. This might include providing a written prescription from your vet, or the company can contact your vet directly to verify.

You will also need proof of your prescription if you opt for Costco pet meds.

Trifexis Coupons And Trifexis Rebates

When you're making a first time purchase of Trifexis for dogs, vets will often provide Trifexis rebates to make the medication a little easier to afford and try out. So make sure to ask your vet about it when it's prescribed!

The same can also be true for Revolution for cats coupons. It never hurts to ask so that you can save a little money!

Natural Flea Preventatives

Some prefer to avoid using chemicals whenever possible on their pets. In those instances, it can be handy to know some of the natural Trifexis alternatives that are available for you.

Apple Cider Vinegar

Apple cider vinegar can be used as a spray for your pet or household, in baths or even in the drinking water of your pets. Make sure that the solution is diluted well, and it can work well to keep away fleas, as they don't like the scent or the taste of it, and will opt to move on.


Fleas also don't like the scent or taste of lemon, so it can be another great option for assisting your pets. Keep in mind that like apple cider vinegar, lemon will need to be re-used and re-applied on a regular basis to keep fleas from moving in.

CBD For Dogs

CBD for dogs is an option rapidly growing in popularity. It assists with a huge number of problems from joint pain to anxiety to even the symptoms that can come with cancer. Consequently, it's an option worth checking out whether your dog is healthy, or has an issue you want to address.

CBD is an amazing resource for pets dealing with heartworm, intestinal parasites, or anything of the like. The reason it's so incredible has a lot to do with the way CBD relieves physical pain and discomfort, making illnesses and diseases more tolerable.

Ringworm, heartworm, and other types of intestinal parasites can cause a lot of physical discomfort for your pet. It's not a comfortable experience, and some sense of relief can do your dog wonders.

That's why we started Innovet Pet. We wanted to make it possible for dogs to experience pain-free recovery from issues like intestinal parasites, worms, and other uncomfortable infections. In 2005, Innovet Pet Products was born.

There weren't enough products out there for pets and the team at Innovet decided to get creative by devising innovative pet products that could address health problems that pets experience over time. Innovet wanted to fill the gap because the perfect product didn't exist. Innovet Pet is a leading provider of all-natural CBD products for pets in pain, whether it's from parasites and worms or other infections that affect their internal organs.

CBD For Fleas And Parasites


While CBD cannot prevent fleas and parasites, it can help your pet to deal with some of the discomforts they can bring. The majority of pain or discomfort in the body comes from inflammation, and CBD is a substance that is able to naturally relieve that inflammation. You can also look at some Natural Pest Control products to help prevent these pesky parasites.

If there are any other issues you want to assist your dog with, it also pairs well with most medications and is perfectly natural and safe.

Top CBD Products

CBD comes in many forms. It's not always just oils! Check out these fantastic products to get your dog the help they need, in a form you'll both love!

For dogs, Innovet sells an array of CBD products for dogs including:

  • CBD oil
  • Advanced mobility support chews
  • Advanced multivitamin soft chews
  • Advanced probiotic chews

  • Advanced calming chews
  • CBD dog treats
  • Soft hemp dog chews
  • CBD peanut butter for dogs
  • Wild Alaskan salmon oil with hemp oil
  • Hemp CBD capsules
  • Dog paw CBD balm


There's not really a wrong decision when it comes to which CBD product you should buy for your dog. It's more of a personal preference than anything else. You know your dog better than anyone, so think about the type of CBD product they would be most likely to tolerate. If your dog doesn't sit still for very long, CBD oil is probably not the best choice.

Dogs that love snacks would take very well to CBD products like hemp dog chews or soft chews. Think about it like that! What does your dog enjoy? From there, once you have an answer, try to look at the available CBD products and choose the item from the list that they would be open to taking.


CBD oil for dogs is a fantastic option for dogs, cats and even horses. It comes in a variety on concentrations allowing for pets of all sizes to get the correct dosage. Using the dropper, you can also easily ramp up the amount used each time and allow your dog to get used to it slowly.

CBD Treats

Innovet also offers CBD dog treats and hemp soft chews that allow you to give your pet an enjoyable treat that provides all the benefits that CBD has to offer. It's a great option for those who want something very simple, that their dog will love!

Trifexis For Dogs: The Bottom Line

For most dogs, Trifexis can be a fantastic option to help with keeping your pet happy and healthy. In most cases, it's pretty easy to give as-is but you can also choose to add it into their food or a treat to make the process a little bit easier. It is a chewable tablet, so there's no worry about having to make them swallow a pill!

If you're interested in Trifexis, make sure to talk to your vet about it. While you're doing that it can also be helpful to ask them about the benefits that CBD can provide. Everyone feels safer about trying a new product on their pet when they know a vet recommends it!
