He's super cute! =)
I understand that you want to keep him away from other dogs, but keeping him away from any other dogs during his learning stage (8-14 weeks) is actually doing more harm than good. He needs socialization! If you have any friends or family with small dogs that wouldn't scare him too much, meet them and allow your pup to interact. You definitely don't want him to be around strange dogs who might have unstable temperaments or are sick, but he needs to be around other puppies and adult dogs ASAP to learn manners... one of the first thing a Mom dog teaches her puppies is not to bite! This is why many reputable breeders keep puppies with Mom until 12 weeks, Mom and littermates have already begun teaching the pups to be gentle with their mouths. I got my rescue pup at 9 weeks, and he was definitely into chewing hands. After a week with our adult dog, and us consistenly "yelping" when he nipped, he does not chew hands at ALL at 15 weeks. Being around our adult dog probably helped the most, because he immediately corrects Fozzie if he bites while they're playing. There is nothing like well-mannered dogs to teach your puppy how to behave!
