We just got a Pit and Shar Pei mix. He weighs about 50 pounds and is 11 months old. He's about 6 inches long and knot about 7“ circumference. Will he get any bigger as he ages?
There is individual variation, certainly, and some dogs go through puberty late, but typically a dog that size would be fully grown, sexually, by 15 or 16 mos of age. I think you could expect him to gain some girth, if he's only 11 mos old, but probably not much more length.
