My Dog Takes Prozac & It Has Changed Our Lives

Happy dogYes, my dog is on Prozac (Fluoxetine). She has been for over six months, and our lives have changed dramatically because of it.

I urge all pet owners who have extreme behavior problems (reactive, anxiety, etc., ruling out health issues first) with their dogs to consider medication as early as possible. The thought of it scared me at first, but I do believe had I been convinced earlier to try it, we could have gotten on a path to happy lives a lot faster.

Close friends & family know Emme is on Prozac, but when I tell others not within our close circle, I usually get funny looks, or scoffed at. I’m told I should train my dog better instead. What these people don’t understand is that all the training in the world won’t help if your dog’s brain is so chemically imbalanced they cannot even begin to learn the right behaviors. The medication helps Emme’s brain allow her to be receptive to the right behaviors. It helps “take the edge off” her anxiety, and helps her be able to redirect to proper behaviors.

Emme CAN BE dog & leash reactive, and had has resource guarding issues. She can also be fear reactive: fight or flight? Emme fights. She is a perfect angel 95% of the time, but put her on leash on a walk when she see’s another dog, and you better be ready. A bike? Hold on for dear life! Lunging, barking, jumping, general crazy. Her reactive behaviors almost never manifest outside our home or outside of walks, which we are thankful for! I can take her to a Rally or Agility competition and she is just fine, walks on her leash perfectly with no reactivity at all. I bring her into work for photos, and she’s a real pro. But, the other issues at home were so severe that our lives were being dramatically affected, and we clearly had to do something.

Allowing her to guard any item (bone, toy, treat, furniture, myself) – is not something we let occur. We train – give her a valued item (chew, etc.) and drop bits of steak as we walk closer and closer to her…Read this wonderful blog post from Patricia McConnell for details on what we did exactly. Nowadays I can take anything from her with no trouble – she is happy to give it up. She has even started bringing us toys, which is a new behavior. She will occasionally guard some new, high-valued item, but we are aware of this and manage it, or use it for a training opportunity.

EmmeGoing for walk is no easy task for us – harness, collar, squirt bottle (of water for other dogs that may be loose, works like magic to keep them away, although try holding on to a barking, jumping wild dog while trying to squirt a loose dog in the face so they don’t get to close…), fanny pack filled with a kong (Em’s favorite toy, useful for distractions), clicker and MANY STINKY TREATS. Then we are off, hoping for the best. We have to keep her under her “threshold” and click/treat so she begins to learn that being quiet and calm is when she gets the reward. It is incredibly challenging, but with Prozac helping, we have better success. I do LOVE an early morning walk, where all is peaceful and no other dogs about, but the walks with distractions are important for learning.

Putting your dog on medication is not something you should do without first ruling out any other medical issue. Take your dog to the veterinarian for a full physical exam, behavior history, and any blood work your vet recommends, including a thyroid panel. If possible, consult a Certified Veterinary Behaviorist. They are best equipped to help you with behavior modification exercises and the right type of medication. (Sometimes several different medications need to be tried to see what works best). We did all of this and MUCH, MUCH more before finally settling on this medication.

I hope we get to where you were when you wrote this! Our dog has separation anxiety. We have done, and continue to do, all things recommended for behavior modification, but she has started trying too hard to get out the front door and there has been blood on the door when we get home. I’ve been taking her to doggy daycare so she won’t be alone, but can’t do that all of the time. She has been on Prozac for a week…it hasn’t really kicked in yet, but I hope it will help Abbey be relaxed when we are gone from home.
