So I have a 2.5 year old intact male Cane Corso on a RAW diet. About 5 weeks ago he started acting almost as if he was scared of his food and whining a lot. Constantly pacing and wanting to go out then come right back in. Does not know what to do with himself no matter what amount of attention, drills, obedience, play he gets. The vet could not find anything wrong with him. They thought it could be a infection so they put him on antibiotics and appetite stimulant and things sort of cleared up but not in its entirety. This past week he has barely eaten as it seems like whatever was going on is back. He has been whining a lot even lying there. Howling a lot at the window. His typical weight is 145-150lbs lean. He was 147lbs 3 weeks ago at the vet and 132lbs today. Vet had no answers other than saying possible colitis and then saying.....well he looks great. Yeah Dr no he does not, you can tell he is clearly too skinny and looks like he is having muscle wasting. I have a few questions. Since he is intact could this be a result of a female being in heat? I have no other dogs but the past 2 weeks at doggy day care (we bring him once a week) there was a female in heat there, separated but all the males were trying to get to her. So this refusal to eat, howling even when I am home with him, pacing, panting, etc......could it be a result of him being around a female in heat? I am not sure if my neighbors have a female in heat and also I live in the country so coyotes in heat could also be nearby. Has anyone experienced anything like this and how did it resolve? I have tried changing his foods, I tried going off raw and going canned food, I have tried kibble, even treats he does not want.
