I haven't used prozac on my animals for fear it will change them neurologically. I have an acquaintance who had a HARD time coming off anti-depressants, so I can only imagine what it does to the serotonin and dopamine receptors more than herbs. BUT I digress, just because I wouldn't use it and I would not reccommend it to anyone without having them try alternate training and other techniques first (like you did with your cats) I think it should still not be taken lightly.
Like, for instance, we know nothing of the routine at Olymp's house in regards of where the dogs feel they stand in the "pack" and who feeds them and walks them and plays etc. . . There are a lot of factors to play into this, I would try positive reinforcement training first and then work from there with natural or chemical supplements. Since Olympia seems to be more favorable to natural solutions in humans I thought there are some holistic things I used that might help :)
As with betta keeping, every pet is different and we all have different methods in dealing with stuff depending on what's available to us! :)
Took Oliver outside again, we were hanging out and a crow was across the street hopping around. As soon as it seen Oliver it flew onto the electrical wire and cawked and cawked and squawked at him like it was raving mad. Then it jumped onto the street and squawked so I took out my phone to video what might happen. Not alot but I'll share it once it uploads to facebook :)
