We took Gunner for a well pup visit at 11 (minus one day) weeks when we first got him. He was 2.6 lbs then. We took him again today (16 weeks yesterday) and he's up to a whopping 3.1 lbs! Both of his parents were in the 7 lb range. Wanna take a stab at his adult weight? I know there is NO way to know for sure. This is just more for fun. My guess is that he'll top off at 6ish lbs.
