Can you see the last couple of ribs when the dog is standing straight, and feel all of them when you stroke the dog lightly?
Is there a pronounced tuck-up? Most bullybreeds should have tuck-up, unless it's a Bull Terrier or something.
Can you feel all the hip-bones when you stroke the dogs lower back?
Can you feel, but not see the dogs vertabrae when you stroke it?
If the answers to these questions are yes, your dog is not fat.
Then again, soo many people have fat dogs, and don't even know it.
It's sad really.
It is specially important that pups of larger breeds are kept lean.
2 lbs of extra weight on the dog, puts 8 (!!) lbs of extra weight on joints that are not finished growing yet.
If your pup it genetically disposed to CHD, osteochondrosis, elbow arthritis etc, extra weight can produce symptoms where there otherwise wouldn't be any. (Oh, and just because your dogs parents don't have any of these illnesses, doesn't mean your dog isn't genetically disposed to them)
Keeping a dog overweight seriously shortens their lifespan, and causes healthissues.
I could go on and on.
Of course, this is directed at anyone in particular.
But statistically, 60% of this boards users have overweight dogs.
The importance of keeping a dog lean, and getting into that habit while the dog is young, couldn't be stressed enough.
Just my 2 cents.
