How big do shar pei puppies get?

Something like that, possibly up to almost 50. My neighbor's shar pei weighs 40 lbs and is a little taller than knee height

30-35 pounds sounds about right, but it all depends on the dog's lineage.

I got a doberman pinscher puppy a couple years ago. He was a little bigger than his siblings, but not by much.
Dobermans are supposed to get up to 70 lbs at most.

He is 106 lbs and as tall as I am when he stands. He is completely purebred and registered, but his breeder was breeding for size.

Make sure you've got a reputable breeder so you don't get stuck with a dog too big for your lifestyle. Just because it's a certain breed doesn't meen it's going to be the right size.
