Hi I have a mongrel 3 year old I adopted from a rescue litter when he was about 8 weeks old. As he grew older he seems more and more nervous and anxious. He is very nervous around people he doesn’t know. He will hide upstairs all day on his dog bed. If he’s called he will look very nervous and scared with tail between his legs and ears back. Sometimes he will even urinate when you try to put his collar on. He will also grind his teeth if you stroke him but he will wag his tail. The vet has prescribed him Prozac. Initially he turned into a zombie and the vet has halved the dosage. We have seen a slight improvement. It has now been 6 months on Prozac and he spends his waking hours staring out of his bed. This is really sad. He is never aggressive and is very social with other dogs. He goes for long walks daily and meets up with other dogs on the beach and is very active, happy and and playful with them. We have two other dogs, one is a 10 month puppy and they are social and play together. As he was part of an abandoned litter his history is known from around 6 weeks old when he was fostered and so no knowledge of mistreatment. I don’t think the Prozac is really helping. Anyone have any further experience ? The vet seems all out of ideas and says the Prozac might be required indefinitely.
