My new guy is far below these averages: 11.6# at 10.5 weeks, 14.6# at 11.5 weeks. Discussing this with the breeder I learned that her pups are always small for their age, but keep growing to full stature a bit slower. She feeds raw and strives to be fairly moderate in amount. People who saw the puppy two weeks ago commented on how much he had grown in 2 weeks...and pictures confirm it. I am quite content for him to be little as long as possible. We've been feeding him lightly the past few days (chicken/rice/pumpkin) which has resolved his puppy squirts, so I began adding 1/4 cup of Blue Buffalo back in with breakfast. Vet in an hour for his 3rd round of shots (and his first visit with them) so I'll have another opinion.
BTW: at puppy class 2 days ago, a man who knew our breeder from shows/Shutzhund looked at him, asked if Yash was his father (he is), looked at his head and feet, and said "He is going to be a beautiful big shepherd". He knew the age of the puppy as well.
