RER = 70 × kg^0.75, times the life-stage factor (Pet Nutrition Alliance). Dogs vary by up to 50%: weigh yours every few weeks and adjust. If you feed treats, take them out of the daily total.
How it works
Resting energy = 70 × weight in kg^0.75. That figure is multiplied by a life-stage factor (1.6 for a neutered adult, 1.8 for an intact adult, 1.2 to 1.4 for an inactive dog, 1.0 for weight loss, 2 to 3 for growing puppies) from the Pet Nutrition Alliance. Treats get 10% of the total, as the WSAVA recommends.
Individual dogs can need up to 50% more or less. Weigh your dog every few weeks and adjust. Check with your vet before a weight-loss plan.
