What are the health issues related to having a dog sleep in a childs bedroom?

We have a two year old puggle. Our six year old granddaughter spends four nights a week with us and wants our puggle to sleep in her room. The dog is bathed regularly, had all her vaccinations, is parasite free and is well taken care of. Our granddaughter has no allergies. The puggle would sleep on a dog bed on the floor. Is there any health risk to the granddaughter by having a dog sleep in her room?
