As a breed, APBTs generally have good muscle tone, and it doesn't take a bunch of supplements and "conditioning programs" to get it to come out.
I find that a lot of people that ask this question are wanting their
to have big, beefy, bunchy, overdone musculature. The APBT
shouldn't be that way. Overdone muscles have a hard time getting rid of heat and reduce agility and stamina -- both hallmarks of the APBT
should be "dry" -- have nice tight skin everywhere, few wrinkles anywhere, tight, dry lips and very medium, "flatter" type muscles -- all the better to be the ultimate athlete that is fast, agile, strong and of great stamina -- all in the same dog.
BALANCE is the name of the game in the APBT
(AND AST). When looking at a good APBT
, no one feature should stand out, but all should blend and balance.
Your pup is very cute; and from what I can see, is not sloppy or of heavy bone -- all good signs at this age.
