My man thing and daughter have both tried out dogs kibble food the few times we have given it. He will eat anything though, she made a horrid face lol I personally wouldn't put that stuff in my mouth because there are very little regulations if any on kibble dog food production, so there's not telling what you could be eating.
if your daughter is eating the pet food, she may be having some type of deficiency... it has alot of sodium and tastes pretty salty, she may be lacking in sodium or some trace minerals found in salts..may wanna check that out
