Negative crease down loin. Ribs very difficult to feel, and fat around tail head very soft. Fat filling area over withers and behind shoulder with noticeable thickening of neck. Minimal, if any, abdominal tuck observable (in nonpregnant animals). May be acceptable (depending on breed, use, and climate) but increased risk of metabolic disease and laminitis and reduced exercise and heat tolerance.
