hi, depending on the age it is absolutely normal, if she is a puppy consider her a baby, babies sleep alot....a puppy needs to rest and not get overly tired. its best to limit the play time, like running to short amounts of time. They can sometimes even get low blood sugar and that can be dangerous. I suggest reading about hypoglycemia in puppies so you will know the symptoms. hope this answers your question. always remember a puppy = a baby..
