Pure bred golden retriever pup

Golden retriever puppy. Last boy in litter. Very smart & lots of puppy energy. We had an unexpected pregnancy & a surprize litter of 7. So, as we are not breeders, we have had an exhausting ride until now. Pups were born the end of Oct. We have had their 1st 2 sets of shots done & they've been given a clean bill of health. They've also been raised until now with cats & kids
