My WL pup is getting big and I see my SchH helper not liking that so much!

He is strong and packs a punch, the mals are welcomed by the helper so his body doesn't break. My pup is agile and fast, but he can stop growing now.
Two of my dogs(I think Onyx is Am pet line mix up) are over the standard for height and the other one is a long coat, big boned female(not sure her lineage) .
I like a smaller dog to be truthful, my foster was a 65# male, easy to manuever around.
Doc, I think most of the breeders are on spring break...where are you going for yours?
