My 5 month old puppy weighs 2lb. 5 oz. and both the breeder and my vet say I will be lucky for him to top out at 3lb. 3 oz. I had hoped for 5-6 lbs. He is so small that the health and safety issues have me scared. He doesn't know he's small and I'm afraid he'll hurt himself or somebody will step on him. He resembles a large rodent since he's so small. I wish my baby would grow to that size
