Puppies learn from mom and litter mates bite inhibition, when playing to rough is unacceptable.
There are many states in the USA where it is illegal to sell a puppy under 8 weeks old.
6 weeks and weighing only 1lb 5oz is dangerous for the puppy. 10 weeks is a lot better than 6 weeks.
To answer your question. Yes he will learn to bite with gentle mouth from other dogs, but those dogs will be more aggressive towards training a wee lil baby what is not acceptable.
Do not leave this puppy unsupervised with your other dogs until they are all 100 % socialized with each other, you could end up with a seriously injured puppy.
Congratulations on your new fur baby. Pan is a cute name for a cutie puppy.
