Question 7

How can I tell if my Newfoundland is overweight?

Accepted Answer

Check three signs: (1) You can't feel your Newfoundland's ribs easily under the fur. (2) From above, there's no visible waist behind the ribs. (3) From the side, the belly doesn't tuck up after the chest. If any of these apply, your Newfoundland may be carrying extra weight. Use the Body Condition Score checker above for a quick assessment, or consult your vet.
