I just introduced a 10 week German Shepherd into my home. He was in a litter of 5. These weight gain charts are terrifying me, because he is 10 weeks old and only weighs 10 pounds. I have read that some 10 week olds can weight twice that. He has been to the vet and has no intestinal parasites. I have documentation of the wormer that was administered via the seller and all. I am just wondering if I am doing something wrong as far as diet goes? I don't want him to become overweight, but I do not want to undernurish him. He is CKC registered and all four grandparents are purebred GSDs (all quite large in size). Am I jumping the gun being worried at this stage in the growing process??
