I just recused a 3 yr she coonhound she isn’t spayed yet last Saturday and it started out great. I drive a school bus so I’m only gone a couple hours at a time. Monday I came home,Marble, Connor and I went on a long walk. Everything was great until around 1:30 and Mable started to chase her tail and howling. I took her the emergency vet and had her checked out and they can’t find any reason why she was doing this. Thinking it was anxiety I was given some Trazodone. I gave her one every hour for four hours with little affect. She also gets aggressive and snaps at me. I was hoping someone else had the same problem that could help me.
