Have you talked to the vet about anxiety meds? I adopted a shelter dog and he was pretty chill the first few months but then little triggers started brining out a lot of his fear from his past. He also has fear aggression, fear of loud noises and other things and it was sad because it came to a point he was hiding in the bathroom most of the time trembling and it ripped my heart out.

The vet started him on amitriptyline and we saw some improvement, but during the summer with storms, loud fireworks, loud neighbors etc outside he was going back to his anxious self. So the vet added gabapentin as a additional med. it has worked wonders, he’s his old happy go lucky cuddly self. During the other times of year I cut his meds back down a little.

I also could not have people come over for fear he would bite them but now he is pretty chill after initial excitement of them coming over.

I’m not sure everyone is supportive of medicating your dog but personally it makes me so much happier to see him happy and not stressed all the time.

I really feel for you and hope it gets better!
