The last time I updated about Napi's progress, I had just had my primary vet consult with the local vet behaviorist. Based on that conversation, we increased his fluoxetine (Prozac) from 10mg to 12.5mg. That was about a month ago, and initially, the dose increase showed some promise. Napi was still barking at things/sounds around the house, but it seemed like maybe it was less intense. On top of that, I was able to interrupt barking fits by calling his name - and he would respond!
But now it's become clear that despite these positive signs, this is NOT the med for my sweet boy. Frankly, he is not very sweet these days. He has gotten more possessive of me; he's growling, snapping, and even biting the other dogs AND my husband if they get too close to me. He's more irritable and tips from excitement to aggression very quickly while playing. He's starting dog fights. It's not good.
So, it's back to the drawing board. We will need to wean off the fluoxetine and then switch to either parotexine (Paxil) or amitriptyline (Elavil). Maisy takes Paxil, so I am biased towards that. The amitriptyline is a TCA - a different class of drug entirely - so it could be a good one to try. I will chat with Dr. Jessy this week and find out what to try next.
