Lucius has vomited 3 times in the past month. Once was in the car and it was HOT outside, so I figure that was just too much for him. (I know I was feeling nauseous in South Carolina hell heat) However, about 4 weeks ago he vomited up a little bit...and then ate it before I could get to it...and this morning he woke me up with a vomit. He's healthy, active, (almost a little too active to be a greyhound...lol) and has not lost weight. The vet says sometimes things just don't sit right so they do that and as long as it comes out and is not constantly hapenning he's ok....but what are your experiences?
