5. Your dog as a blocky body shape
Humans put entirely too much emphasis on imagined or unrealistic ideal body types enforced by popular media.
Despite the wide range of frames and body types among dogs, there does tend to be a typical healthy body shape.
Look at pictures of dogs in profile. Regardless of breed, you’ll notice a distinct upward slope from the base of the ribcage to the hips.
The degree of that slope varies, but is usually noticeable. A blocky, endomorphic dog with no difference in girth from ribs to hips is likely to be dangerously overweight.
