I am really glad that your husband asked, I wish I would have known everything to ask when I first got Homer, he was so tiny and they didnt break up the shots. He had a really bad allergic reaction and would have died had I not rushed him to the emergency room. With the rest of his shots and all of Kady's I make sure that they give him 1/2 one week and the other 1/2 the next. My new vet also likes to keep the little ones for a few hours to observe them. It is very scary when you dont trust your vet. If I were you I probably wouldnt return to that vet again.
