Pups on this page should be 4.5 lbs or more. Any estimated grown weight listed with a pup is only my best guess and not a guarantee number. To get a close estimate of the future adult weight of a pup, times the 8 to 9 week weight by 3, or times the weight of a 12 to 13 week old pup by 2 to get a ballpark estimate.
(2 lbs @ 8 weeks =6 lbs grown) (2 lbs @ 12 weeks=4 lbs grown)
