My chocolate lab Toby, growth chart?
I was just curious as to what age do lab puppies usually grow up too? My lab just turned 7 months and he 69 lbs. Should I expect a lot more growth and weight gain or should he hover around that for a while?
He'll be full grown at around 2 yrs old. Of course he's going to get bigger somewhat and gain more weight.
