Many different things. You need to have a vet see your puppy to know for certain and to get the proper treatment for the puppy's rash.
A dog is a puppy until it reaches one year of age.
could you be more specific? do you mean in a dog show or just shown to another person?
If it`s a small puppy 8 weeks is the right age, but if it`s a large puppy it can go as early as 6 weeks.
Never vaccinate a puppy before 6 months of age because they are still developing and could conceive and are put at risk of a illness because of youth.
Any puppy who will not eat or drink needs to see a vet. Could be anything, but she needs to be checked.
About 8-12 weeks
a puppy age is week old
yes, a puppy IS a dog up to 9 months of age.
you can tell by opening the dog's mouth and looking inside. when you see that the teeth are quite imature, you'll know you're puppy is about 6-12 months of age. As it grows it will grow much in it's jawline, so look out for that, too.
You can be any age as long as you understand how! I don't think a child under 3 could understand.
