My dog is 70 pounds and was given 300 mg of trazodone does this seem too much? Wednesday night he sliced his poor open on Sharp piece of ice when we went to the emergency clinic they tissue glued and clotted it with a bandage today we went to the vet we normally visit and she cleaned it and re-bandaged it after stapling it shut she then prescribe Rimadyl and the trazadone. Just thought 300 mg was a lot..
