What type of dog is this?how do i train him?

OMG i just melted when i saw those pics! too cute! it's a little too early to make an accurate guess on what breed he is. he looks extremely young like 8 weeks old. maybe not even that old because my beagle was bigger than this at 8 weeks. has he had all puppy shots? i would definitely recommend taking this lil guy to the vet to have a checkup. the vet could give you some good advice on training too. i'm not sure how to deal with biting other than being really firm with him. your dog has to respect you in order to do that be very dominant and firm.
