you know when puppies eat and drink to quickly and they sort of heave and go out and eat some grass..and then throw up...well my dog has been heaving on and off for 3 days now>> she's done this before..but it's a bit more frequent...her mood is fine, her appetite is fine and her stools are firm..i think she had full anal glands the other say because she was scooting a lot and her poo had this sort of mucus in it...does this have any relevance? anything to be concerned about?
