6 month old Aussie

Question
I was wondering what the appropriate height/weight is for a standard male 6
month old Aussie puppy is..? He just turned 6 months old and currently weighs
38.6 lbs and is 19 3/4 inches tall.  Is his weight normal along with his height.  
We are hoping to show him so do you think he will be 50-60 lbs and 20-23
inches tall?

Answer
It sounds like he is on a growth curve that would place him in the mid to high end of that range.  However, that's just a guess, and some dogs will surprise you.  If you know the size/weight of his parents, that might give you some added confidence about where he might end up.  Hopefully, you purchased from a responsible breeder, who can also provide some input based on knowledge of your particular pup's lines, and how they normally mature.
