Like humans, dogs of an ideal weight will be healthier and live longer.
Ideally, when trotting, the dog’s ribs should be just visible.
If the dog is overweight, the ribs will not be visible when trotting. Simply feed less food at each meal, and be sure to follow the exercise guidelines, keeping the balance the same if feeding BARF.
If the dog is underweight, the ribs will show when standing. Increase the food at each meal a little (for example, if giving 1.5 patties each morning, give two patties instead). Over time, this may cause the dog to become overweight, so be sure to monitor closely and adjust to suit.
