I can't stand it. Barkley has this fishy smell every now and then. I have no idea what it is. My only thought is that maybe it is anal glands. He is fixed and has been since he was six months old. I have had male dogs( alwasys neutered) in the past and have never had to address an anal gland issue. I guess I wondered if this could be it because I have heard that it is a stinky smell. It isn't all the time that I smell it-but when it stinks-IT REEKS! Does anyone know anything about this? I don't think it is gas because I am quite familiar with that stink. This smells like old fish.
