So, a quick backstory for everyone who doesn't know: Milo, my 7 year old pet store/puppy mill JRT (mix?), has had a plethora of mental issues for his whole life. Anxiety, panic attacks, OCD, and aggression induced by all of this. We've managed it his entire life with some behavior modification and lifestyle adjustments. It's difficult, because my family is not on-board with a LOT of training, and as most of you know, it only goes so far when it's inconsistent. I'm expecting a baby in June, and my parents (whom I live with), paid for a behaviorist. I figured that if they were willing to pay someone just short of $1000, they'd LISTEN TO HIM (I was wrong). The dr prescribed prozac, as well as developed a behavioral modification plan. Milo started taking the prozac about 5 days ago. His behavior has improved very slightly, but I'm attributing that more to behavior modification than the meds. It certainly hasn't gotten worse. I know it's too soon to see much change. The problem is, since starting the prozac, he's been acting REALLY off. Not aggressive or anxious...just sad, lethargic, and not himself in a bad way. He'll actually go into the bedrooms to sleep and be away from the family, which is something I've never, ever seen him do. He hasn't played with toys AT ALL in five days, which is not like him. His appetite has greatly decreased - he will still take high value treats during training, but is uninterested in most average treats (he could stand to lose weight, not super worrisome on it's own). If he is around the family, his ears are back the entire time, his expression is just dull and sad. I've never, ever seen this dog look sad before. I've honestly never seen his tail stop wagging while he's awake, ever. It's been barely wagging at all. He doesn't want to do anything. Normally this is a dog crashing into the door and jumping to go outside, racing around with a toy, licking everyone's face, into everything...he's just lying around. I'm going to call the Dr tomorrow and ask, but I'm considering just halving the dose before even talking to them. He's on 10mg, and he's a 20 lb dog. When I was on prozac, I took 20mg, and I weigh 6 times that much. I don't know if he's on such a high dose because of the seriousness of his issues, or what. Has anyone had an experience like this? What did you do? Did the dog "get used to it" or did you need to change the dosage? It's breaking my heart to see him like this.
