Hey everyone! New to the GSD puppy world and new to this forum. I’m constantly searching the internet for the best way to feed my puppy. He’s 16 weeks 37 lb. As of right now I’m feeding him a mix of his 2.5 cups of kibble and 3 cups fresh boiled ground beef spread between 3 feedings. He’s no where near showing any sign of being overweight.. just growing very fast. The problem is the past week He still seems to be very hungry between feedings. He’s never done this before. Is this normal? Should I be feeding him more during these times? I was thinking maybe it was a growth spurt?
