growing?

I have noticed the past couple of weeks that my appy (turned 5 in Feb) is growing....his butt is a little bit higherthan it was previously! Is there any growth supplement I can give him during this growth period that may encourage his withers to catch up with his hiney???? (Fingers are crossed)

I am hoping that "butt-high" is not his destiny!

Not really anything to give - just make sure he gets enough food and a proper balance of nutrients is your best bet. If he is genetically destined to be rump high there is nothing you can give to counteract that. However, don't worry yet - he still has some growing potential left. If he has been relatively even up to this point he most likely will even out again.
