For years, fluoxetine (Prozac) has been pushed as the answer to behavioral problems in dogs. Veterinary behaviorists and force-free advocates love to cite “science-backed” studies to justify long-term medication use. But here’s a big problem, most of these studies are flawed, biased, and rely almost entirely on owner-reported data.
Take, for example, the 2009 study on fluoxetine for compulsive disorders in dogs (Irimajiri et al., J Am Vet Med Assoc). It claimed fluoxetine helped, yet the only improvement came from owners’ OPINIONS, not actual behavioral measurements. When researchers looked at objective data the dogs’ actual behavior logs they found NO SIGNIFICANT difference between the medicated and placebo groups. But guess which result gets cited?🤫
How about the 2007 study on fluoxetine for separation anxiety (Simpson et al., Veterinary Therapeutics). The conclusion? Fluoxetine was effective … but only when paired with a structured behavior modification plan. And yet, thousands of dogs are medicated without any meaningful training, as if a pill can replace actual learning.
Sad reality is that Dogs are being drugged, not rehabilitated.
Ask any serious trainer what happens when they get a dog that’s been on fluoxetine for years. They take the dog off the meds, implement a sound training plan, and SHOCKINGLY the dog improves.
Not because fluoxetine “worked,” but because the dog finally got what it needed: clarity and proper training.
Yet, the AVSAB keeps pushing these medications while dismissing legitimate training as “aversive” or “outdated.” They’d rather chemically suppress behavior than actually address it.
The real question isn’t whether fluoxetine has some effect but why so many dogs improve when you REMOVE the drug and train them properly?!!!
Behavioral change comes from learning, not sedation. It’s time to stop pretending otherwise.
I know I am not the only one noticing that dogs on fluoxetine don’t get better - they just get dull.
The dog isn’t learning or adapting, just becoming more passive.
This can actuallY DELAY proper rehabilitation, because the dog’s emotions and responses are chemically suppressed rather than modified through learning.
Thinking about making a solo podcast to talk about the dog I have in training right now, one of the many that end up euthanized after YEARS of being on SSRI’s and the pandemic of prescribing psychotropics like flea medication
