I have had my cocker spaniel puppie for 2 days and since we got him home, he has been sick 3 times and keeps vomiting. He keeps crying! He is eating and drinking fine and doesn't have diahorea. I am really worried about him, please can you help me?

Have you taken him to a vet? That's your best bet, we cannot give you a diagnosis over the internet, it would be a guess at best, which isn't going to help you or your pup. The vet will be able to run tests and find out if anything is wrong. Best to get it checked now, puppies can quickly develop serious illnesses, the sooner it is caught, the better the outcome. I'm not saying that your puppy is sick, but better safe than sorry.

Good luck.
