Guessing you are asking if you can make your cat regurgitate/vomit, ie if you think they've ingested something dangerous? There are substances you can feed them to trigger it, any poison control centre would be able to tell you.
Why you ask?? I think how they get sick is depending on what they eat. If you feed them bad things like grass, chocolate and grapes, they could die. Be careful It might also get sick if they eat the wrong kind of doggy food. Sometimes the puppy might have stress too. I think that it can get sick if you feed it regular dog food when they are young. And if you feed it a whole different kind of thing. (example, you have been feeding it dry food all your life, but suddenly you feed it wet canned food.) Im not so sure but I have been researching puppies.
Like people, there are several things that can make a dog sick- eating too much, or eating the wrong things is high on the list. NEVER give your dog chocolate, and watch for leaks of anti-freeze from cars- it tastes sweet, dogs like it, but it is poisonous. Dogs also need fresh, clean water. If your dog is seriously sick, you need to have a vet see your dog- there is not a lot we can do at long range, since we can't see of examine your dog. Wish I could help more- sorry-
feed it chocolate which would probably make him die. So don't do it.

Not unless the puppy is very very sick and even then, most diseases a puppy can get are not transferable to humans. Canine to human pathogens are rare. The benefits of a puppy /child relationship far outweigh the dangers of the child ever getting sick from interacting with a puppy.
