Could feeding a dog a meal that is too large cause them to vomit? I feed my Standard Poodle a chicken quarter per day along with some boneless meat and organs. I don't typically feed her this all at once because it seems like a lot for one meal. Today I fed her a chicken quarter then a few hours later I gave her a slice of beef heart, a small amount of beef liver and kidney (maybe enough to fit in a tablespoon) and some canned mackeral (I have not been able to find whole raw fish around here) Around three hours went by and she vomited up all of the second meal that I gave her. Is this simply because she had too much food or perhaps because I didn't space out the time between meals enough? The chicken quarter did not come up, just the second meal. This is the first time she has had any problems since being on raw and she has eaten all of these things in the past.
