I can sympathise... my first Mal boy grew extremely fast and when I look at other Mals of 6 months, or even when I think of my second, I can't get over the size he was!!! However, this has caused problems because he came back with a high hip score... even though his parents and siblings are low scores. When I've done research into it, there is a discussion into whether fast growth in puppyhood can affect the hips, which is why I said the weight at his age could cause problems. I don't know Hills, but it may be too high in protein?
Good Luck this weekend, hope you do well :)
