Hi. My puppy who is nrly 17 weeks old was sick this morning and when we looked he had also been sick once in his bed last night? I've never had a puppy before, should I be worried? As far as I'm aware he hadnt eaten anything different but he does have a tendency to eat anything? I'm not sure how he has been today because he is with my boyfriends parents. Any advice?
He may have picked up a bug, or eaten something that you don;t know about that has diagreed with him.
Dogs are good at vomiting out anything that upsets them - if he seems OK, and is not listless and / or off his food, then it's probably OK. If you are unsure, or he has either of those symptoms, take him to the vet to be checked out.
