I keep one dog inside, he's on grind raw meat all day, and once in a while i give him something to chew on like a chicken leg, added with some liver and vitamin mineral complex.
Now i notice, 5 out of 10 time in the morning after he ate a leg, he needs to throw up. It looks like when a dog throws up with an empty stomach and sometimes there also 1 little piece of bone with it that isn't digested yet.

I was thinking, maybe he has some trouble with more sour that's in need to digest with the leg, then he usually needs with the raw.. which digest allot easier.

Any thoughts?
