throw away account here, I'm worried about my male GSD being too small. his height seems below average, too. He honestly looks like a 4 and a half month old pup. he just turned six months, and the last the vet weighed him was at actually 4 1/2 months, he was 30 something pounds then. is this normal? im very worried, and is there anything i can do to help him grow? i know genetics play a big role in this, yet i need some words to put me at ease.
