Hello all new here! We just picked up our GSD from the breeder. He’s doing great! Very playful and napping a lot! One thing we’re concerned about is his weight. He’s currently 8lbs at 7 weeks. I see growth charts online and they say he should be more around 19lbs! He’s German show lines. If that makes a difference. Just concerned that he has a weight problem. His two brothers looked to be about the same size so I don’t think he was the runt per se. any help is appreciated!
