Prozac Side Effects for Dogs

Much like humans, dogs can experience a wide range of feelings including depression, anxiety and stress. Similarly, they may not know how to handle these emotions, which can result in some negative animal behaviors. Because they cannot tell us about the emotions they are having, we can often discover the stress or dog anxiety through those behaviors.

When your dog is misbehaving, spending a lot of time barking, chewing, pacing or displaying other anxious signs, it's a good idea to take a deeper look into what may be going on. If dog owners decide to go the medical route, the veterinarian may prescribe tricyclic antidepressants or other medications. Dog prozac is one of the most common canine anxiety medication, but it's important to work with your vet to find the right option for your dog. With a little patience and trial and error, you can help your furry friend find relief from anxiousness.

What Is Prozac For Dogs?

Prozac is a medication aimed at helping to provide dogs some relief from anxiety as well as depression. Humans are also known to use medications like these for similar purposes. By enhancing the activity of a neurotransmitter called serotonin, found in the brain, this medication can be useful in keeping dogs calmer and happier overall.

Knowing how Prozac works is important for ensuring that your dog receives the best results, whether you choose to use brand name or generic Prozac. Options like fluoxetine for dogs, trazodone and lovane are all options your vet may prescribe. There are many who prefer a prozac generic product, as they can prove to be less expensive.

Many pet owners are left wondering what they can give their dog for anxiety, and in truth there are actually many options. Prozac for anxiety can be quite useful, but it's important to follow instructions for the medication very well. Understanding the Prozac or Lovan side effects, the Trazodone dosage for dogs and how to avoid a Prozac overdose is key to keeping your dog healthy and happy.

Whether you're using Prozac, fluoxetine for dogs, or another variety of the medication, it's important to understand as much as you can about the medication.

Prozac For Dog Anxiety

Dogs have a wide variety of different personalities, and the experiences they've had in their lives can effect them in much the same way that our experiences effect us. Because of this, some dogs may be more prone to anxiety than others, which can present itself regularly or just during certain times like when they are left alone, or when things like thunder or fireworks are present. 

When dogs are feeling anxious, they may begin to behave in unwanted ways. They may have accidents, bark frequently, or damage household items. Before you get mad at this behavior, take a moment to consider why it might be happening.

For things like separation anxiety or agitation that is particularly intense, your vet might choose to offer a prescription for something like Prozac. Basically, this medication inhibits the absorption and the processing of serotonin, limiting the anxious effects that it can cause in your dog.

Prozac For Dogs Uses And Doses

The instances when Prozac may be used for dogs can be different than what you'd find in humans. Furthermore, the dosages dogs require are also going to be very different. The following will help to guide you through when your dog might need Prozac, and about how much may be prescribed.


Some of the common reasons your dog may be prescribed Prozac include:

  • Separation anxiety
  • Phobia of people, thunderstorms or other specific things
  • Compulsive disorders
  • Aggression
  • General anxiety
  • Excessive urine marking

If your dog has any of these behaviors, make sure to discuss possible solutions with your vet. Prozac, or similar medications, such as Trazodone, can put a dog to sleep, so make sure to watch out for added drowsiness as well.

Prozac Dosages

The dosage that your dog may need is going to be different from what you might be prescribed, so it's important to follow your vet's instructions while administering it to your pet. They will be able to guide you to the correct amount.

It's worth keeping in mind that Prozac is addictive, so your vet may want you to slowly wean your dog off of the medication when they are finished with it. Prozac for anxiety can make dogs feel sleepy, so it's important to make sure dosages are handled well, and that you ask your vet when the best time for your dog to take Prozac is, as well as what to do when stopping Prozac.

Dog Prozac Vs. Human Prozac

Human Prozac should not be given to dogs under any circumstances. When you do this, you create a much higher risk of overdose, as well as create the possibility that your dog is receiving medication they do not need. If you think your dog may need Prozac, make sure to get them to a vet.

Prozac Benefits For Dogs

In recent years, there's been an increase in the number of pet prescriptions for anxiety disorders and other behavioral issues. Prozac is one of the most commonly prescribed meds for dogs. It's one of many controlled substances that's meant to be used alongside a behavior modification program. The medication can help to calm nervous dogs who are experiencing anxiousness and reduce the effects of compulsive behaviors, such as excessive licking and urine marking.

Prozac can also be helpful for dogs who tend to urine mark inappropriately, like in the home. However, it's important to note that this medication is only meant to be used as part of a comprehensive treatment plan that includes behavior modification training. Otherwise, the medication will not be effective.

Does My Dog Need Prozac?

In some cases, dogs who experience the issues listed above may be able to work through their issues in other ways, such as through training or other medications. If your dog experiences any of those symptoms, then talk to your vet about it and they will help to provide effective options.

Prozac Side Effects

Like many other medications out there, Prozac does come with a list of possible side effects. Some of these may be more dangerous, while others are more mild. Because of this, it's a good idea to have an understanding of the possible side effects of Prozac that your dog might experience.

Some of the side effects in dogs include the following:

If you notice that your dog is having an intensely bad reaction, or even more standard side effects in high amounts, like vomiting or diarrhea, it's best to contact your vet.

Avoiding The Side Effects Of Prozac

A useful way to determine whether or not your dog might have some unpleasant side effects is to note any conditions they may already have. This might include being finicky, experiencing liver issues, or having a stomach that is easily upset. 

If your dog already experiences issues like these, then giving them Prozac can potentially exacerbate the conditions and create nasty side effects. If your pet has diabetes mellitus or seizure disorders, they may be especially susceptible to side effects from Prozac. Canines with liver or kidney disease may not do very well on Prozac.

If your dog doesn't have any of these kinds of conditions, then they can still be subject to side effects. The lack of those conditions just means that it's less likely they will have serious issues with the medication. As with any new medication, make sure to keep an eye on your dog to make sure they are handling it well.

Types Of Anti-Anxiety Medications For Dogs

Because medications like Prozac can come in generic as well as brand name forms, it's important to know what types are out there. Prozac is the most well known, but it is just a brand name for a drug called Fluoxetine. You can also find another brand name of this medication known as Reconcile for dogs.

Natural Anti-Anxiety Options

It's wise not to focus on using medication alone for the sake of managing your dog's anxiousness. Often, medications work well as bandages, but do not heal the deeper issue. Consequently, the following options can help to relieve anxiety in your dog for the long term.


Anxiety often comes with a lot of excess energy. When that energy isn't used in a productive way, it can result in a greater amount of anxiety and the destructive behaviors that come with it. Making sure that your dog is getting daily walks and playtime can help to decrease their anxiety levels. 


Some types of anxiety can be adjusted through the use of training. This is particularly true when your dog is afraid of something specific, like separation, travel or thunderstorms. Find ways to connect these events to positive experiences in your dog, and in time they'll be less afraid of it.


While diet isn't often the only change your dog may need, it certainly doesn't help to make sure they are on a healthy diet that works well to suit their needs. In some cases, you can even opt for a prescription food that includes calming ingredients!

It offers a calming result, which is fantastic for dogs that tend to be very wound up. Just a little bit goes a long way, and for most dogs the worst side effect discovered so far is that higher doses can result in a little bit of sleepiness.
