they grow at different rates..some do most of their growing the first 4 mos. then slow down, others keep growing..Mine was around 7 lbs at a year, now at 5 she's 13-14 lbs. but, I've also seen some big pups, that have ended up being pretty small full grown. You have to remember, they used to breed them big, and there are still throw backs..my 14 lb'er came from 4 lb parents |
