Fluoxetine is an antidepressant belonging to a group of drugs called selective serotonin reuptake inhibitors (SSRI). Fluoxetine is used in dogs and cats for the treatment of canine aggression and obsessive-compulsive disorder. Fluoxetine requires a prescription from your veterinarian. Tablets are sold individually. When veterinarians prescribe Prozac (fluoxetine as generic) for dogs, it’s the same medication you would receive from your doctor for a similar issue—just in a different dosage. It’s a selective serotonin reuptake inhibitor (SSRI), meaning it blocks your body from reabsorbing serotonin. When levels of this neurotransmitter are higher in the brain, it’s thought to improve mood. Does your dog need anti-anxiety medication?

Before prescribing anti-anxiety meds, your vet needs to rule out a medical cause. Dog anxiety can be triggered by internal issues such as irritability caused by allergies or even pain caused by osteoarthritis. Once an underlying condition is ruled out, a veterinary behaviorist will assess your dog’s social and environmental history and anxiety episodes. “It’s not really always about figuring out the ‘why,’ but how to move forward,” Dr. Pike says. A diagnosis—such as fear-based aggression with people and dogs—will be followed by a prognosis. A treatment plan including medications and behavioral modification will also be made.


Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) that is prescribed to treat a variety of behavioral problems caused by separation anxiety and obsessive-compulsive disorders. It works by increasing the effectiveness of serotonin in the brain, which aids in the management of anxiety and depression. Customers may receive this drug under the names Reconcile, Prozac.
