Does anyone here have experience of SSRIs for fear aggressive / reactive dogs? I have a seven year old dog who is very highly strung and can be prone to fear aggression. I've spent many hours working with him (with the help of a behaviourist), and we also work hard to effectively control his environment so he is less trigger stacked. But - he is still very easily tipped over his limit. I just want him to be happy and am wondering if SSRIs may be the answer.
