Height comes first, then muscle mass, and the head usually stops growing (muscle mass included) about 2 years. I specifically asked my vet about the head growth rate when I had my show Giant Schnauzer, because her ears tended to touch at the tips when she was very keen on something. He said that once her head and the muscles in the head stopped growing at about 2 years, then I could start to worry if they still touched.
Dunno when the feet stop growing.
