When The World's Greatest Dog was about nine weeks old, we gave him a treat that disagreed with him. Poor little man was so sick for an hour or so, trying to expel that thing from his system any way he could. He begged to be let outside to do that--didn't quite make it the first time, but the rest of the time he did. We'd see him gag and then run to the door, and he'd run outside to vomit. That was a nine week old puppy. Yes, and incredibly smart puppy--and I swear I am not exaggerating that he was housebroken by the end of his first week with us, although he had one or two accidents after that when our daughters didn't catch his signals--but still a puppy, who had only just understood that elimination of waste was to be done outside. We did not expect him to understand/make the connection that vomiting should be done outside, too...but he did. It might have been pure instinct, of course, but the fact remains that he did not want to throw up in the house or on himself. So a nine week old puppy was able to control his need to vomit better than this fucking slob.
