Hi all, I have a 6-year old male Bichon Frise, a 4 year old female Bichon Frise and a 15 year old female cockapoo. My problem is when I put all 3 dogs in their pens when it is time for them to eat my male Bichon (Toby) just stares at his food as he knows if he holds out long enough I will let him out of his pen, which is my fault, so he can eat his "sister's" food, our 15 year old cockapoo. I feed them all the same food, Kirkland's small dog food, which they like, but for some reason Toby at times will spit up. I know he eats fast as he thinks he might be missing something and I give them all a reasonable amount of time to eat but not sure why he is doing this. I told the vet the last time we were there and he really did not have an answer. I do not know if I should change food for him and just leave him in his pen until he gets hungry enough to eat or just what to do.
