It can definitely come as a surprise that our fuzzy best friends can experience frequent sneezing, uncomfortable, itchy eyes, or even the unpleasant skin symptoms that can come with them!

Part of the reason we don't tend to notice allergies in dogs as much is because they can show their symptoms in very different ways from ourselves. However, they can still have just as much of an effect on them as they do when we experience them.

Unfortunately, our dogs aren't able to speak up and let us know when they're feeling those effects. You might be wondering, what could possibly be the answer to such an issue?

Does Your Dog Have Allergies?

Dogs can have allergies the same as we can, though they might show up in some different ways. Just about anything out there can cause these allergies, and it's a little different for every dog. It can also be common for some allergens to effect them more than they do us.

What Are The Symptoms Of Allergies In Dogs?

Some of the common symptoms you might see if your dog is dealing with allergies are:

  • Swelling
  • Gnawing at legs and paws
  • Skin irritation or redness
  • Excessive face or muzzle rubbing
  • Excessive itching of specific areas

Depending on the seriousness of the reaction, some dogs can also suffer with more serious effects like hives or anaphylactic shock. If you notice the latter issue in your dog, it's exceedingly important that you get them to the vet as soon as possible, as it can be just as dangerous to them as it is to us.

Consequently, it's very important to make sure you look out for allergies in your dog. While some might be just a small annoyance to them, others can have fatal consequences if left unchecked. Of course, the number one priority is to keep your canine buddy happy and healthy!

Just like us, dogs can experience allergies that come from the world around them. Things like pollen, grass, dust mites and more can begin to irritate them. In addition, they can also experience allergies that come from flea bites, which can make them itchy and sometimes even result in hair loss and scabs.

In other cases, dogs can also be allergic to the food they eat or some of the ingredients in it. This can sometimes be much more concerning, so if your dog seems troubled after enjoying a meal, make sure to keep an eye on them!

How Are These Allergies Treated?

There can be a number of different solutions provided for your dog when they are experiencing allergies. Largely, it depends on the kind of allergies they're having and if the source of that allergy can be removed. If you're familiar with the ways Zyrtec can help people, then you might be wondering, "Can I give my dog Zyrtec?"

What Is Zyrtec for Dogs?

Many of us are familiar with Zyrtec as a medication that assists with human allergies. Those who have allergies can find that this over-the-counter option is one that allows us to deal with seasonal allergies much more easily. What users often enjoy about it is that it not only does away with irritated eyes and stuffy noses, but does so without making us drowsy!

Typically, this is a product that is intended for humans. Therefore, it isn't certified by the FDA for use in our pets. However, it's a choice that vets are going with on an increasing level for allergic reactions and itching in pets.

What Are The Uses Of Zyrtec For Dogs?

Zyrtec may not be prescribed for all situations, but it can be one that is prescribed when your pet is dealing with atopic or contact dermatitis. They find that it can certainly help with things like swelling, dog hives and general itchiness that can occur when coming into contact with an allergen. Overall, Zyrtec is a rather useful antihistamine for your dog, capable of a lot of benefits.

As with any medication your vet might prescribe, it's a good idea to know what it is, what it's for, the ingredients it may have and the side effects that may show up in your pet. That way, you can be armed with the knowledge to make the best choice for your furry friend.

If you're curious about using generic Zyrtec for your dog, it's best to check the ingredients to make sure they are safe as well as ask your vet if it will work just as well as standard Zyrtec for your dog.

What Is Cetirizine?

The active ingredient in Zyrtec is cetirizine. Among other Zyrtec ingredients, this antihistamine strives to keep histamines blocked. As a result, cetirizine for dogs able to lessen or avoid allergic reactions that occur because of the release of these histamines.

Antihistamines including Benadryl and Zyrtec are pretty common in human medication, and tend to be pretty useful in keeping our allergies at bay. This particular ingredient can also be found in Children's Zyrtec Hives Relief, Aller-Tec, Children's and Adult Zyrtec Allergy, Wal-Zyr and PediaCare Children's 24 Hour Allergy. There are few allergy options this ingredient isn't in!

The Dosage Of Zyrtec For Dogs

The Zyrtec dosage for dogs needed can vary quite a bit depending on their overall size. Consequently, it's best to follow your vet's instructions when it comes to this product. When it comes to an allergy medication like this for dogs, it's best not to try to guess the correct amount.

Furthermore, the correct Zyrtec dose for your dog also takes into account the symptoms that your dog is experiencing. Consequently, your dog will need more or less of the medicine depending on whether they just have some skin itchiness, or something more serious like a bee sting. It can be hard to get the right amount without the help of a vet who understands the medication. Under the guidance of a vet, you can also use Zyrtec for your cat as well!

Zyrtec Precautions for Dogs

On top of the more standard side effects that can occur, there can also be some more serious ones that are extremely important to keep in mind. Zyrtec for dogs can sometimes have unintended effects that are quite frightening.

For example, some dogs can experience urine retention. As a result, it can really cause issues for dogs that might already have some problems in their kidneys. This is also true for dogs that may have issues with their liver. While those problems may not be serious just yet, using the medication can exacerbate the situation.

Dogs that are nursing or pregnant would also do best to avoid these kinds of medications. Puppies that are still nursing are far too young for these kinds of medications, and the current studies for using Zyrtec with pregnant dogs are sadly lacking.

Before giving your dog Zyrtec, it's also best to make sure that your vet is fully aware of every other medication or supplement that you use with your dog. That way, they can decide whether or not those other medications might not mix well with the Zyrtec and make adjustments accordingly.

Side Effects Of Zyrtec In Dogs

Side Effects Of Zyrtec In Dogs | Innovet Pet

If you don't have any concerns for your dog having serious liver or kidney reactions, and they aren't pregnant or nursing, then it's still worth keeping the more standard side effects in mind. For the most part Zyrtec shows itself to be relatively safe when it comes to intense side effects.

That said, there are a few concerns worth noting to be sure your dog is safe. Research has been conducted, which shows that only about 30% of dogs tend to get the benefits of antihistamines. In addition to that, up to about 25% can also have some unpleasant reactions.

It's also worth considering that antihistamines aren't a cure for the allergies your dog may be experiencing. Instead, they are somewhat of a Band-Aid. What that means is that they can help with lessening the symptoms, but they definitely won't stop the source of the problem. As a result, if your dog has something more going on than just a small seasonal allergy, it can end up going unchecked.

For the most part, dogs that experience side effects while using Zyrtec will get sleepy. In itself, that isn't the most serious of side effects.

However, they can also experience:

  • Urine retention
  • Constipation
  • Excessive salivating
  • Vomiting
  • Impulsive reactions

On top of that, it's worth keeping in mind that the use of Zyrtec can also result in issues that are quite serious. These can include liver and kidney problems, which can end up becoming much more of an issue than a simple skin allergy.
