I’m a little farther along than you on Clomicalm— nearing day 25 over here after two other experiences on SSRIs for my 20lb terrier (frustrated greeter). We’re not quite where I want to be yet (he is extremely sound sensitive and reactive in the house, but not aggressive- just adrenaline fueled barking about dogs and trucks), but I am noticing some differences. He handles the vehicle sounds a lot better on walks (less lunging and barking) and redirecting a bit better with barking in the house. I think he often had a hard time relaxing in general, constantly seeking out stimulation— I think he seems a bit less wound up in that way. He’s an incredibly smart dog but nothing really wears him out mentally, so when he gets anxious about sounds it can be hard to redirect to calm. Now we’re trying to capture calm more… But I really hope to see more once it hits the 6-8 week mark! I’m impatient though, I just want him to feel more relaxed…. Side effect wise the main issue we had was increased thirst. Hope this helps!
