i think it depends on the hertitage of your pup..i dont know about your breed exactly mostly i know labradors and pointers..a lab is close in size and that sounds about right..girl dogs reach their max around 6-8 mths where a male lab grows up for the first year (height) and out for the second (muscle and dense bone) they thicken like human males do. A male labrador can run from around 75 on the small side to around a hundred on the very large side. Since the two breeds are both heavy boned i am sure that is a close proxy.
