Thank you for the answers.
If your pup has not had all his vaccines he should not be walked outdoors or be in a yard, he needs to stay indoors until he is fully vaccinated. He should get his rabies and distemper shots at 16 weeks old, to take him outdoors without these vaccines he is at risk of getting rabies, distemper and / or parvo. Back yards you have disease carrying animals, squirrels, mice, moles, voles, chipmunks and what ever wild life in your area, stray cats with fleas can visit your yard subjecting your puppy to getting them also.

Don't chase after him to pick him up, most puppies see this as a game, in your pups case it is scaring him. Do as you have been doing, sit on the floor and entice him with his favorite toys, have treats with you to reward him when he comes to you.

You only have him appox one week, some puppies need more time to adjust to new home, smells, sounds, different human voices. Keep the bedroom closed as you're doing. Just be patient and cheerful he has to build trust in you, he will come around.

Please, no more outdoors until he has had his last vaccine, not even your back yard.
