Estimate how many calories your dog or cat needs each day.
The energy formula uses a different set of multipliers for each.
It doesnβt change the formula β it gives us a published healthy adult weight range, so we can estimate a weight if you havenβt got one.
This is the multiplier applied to resting energy. A growing puppy can need two to three times what a neutered adult of the same weight needs.
Body conditionWeight alone canβt say whether to feed for maintenance or for loss. Look from above, feel along the ribs, and pick the shape.
Everything is calculated per kilo of body weight β this is the number the answer rests on.
Treats should stay under about 10% of the dayβs calories. We take your share off the meal rather than adding it on top.
It changes which foods could suit. It doesnβt change the calorie figure.
So a portion can be worked out for the food you already buy.
A starting-point estimate using the WSAVA RER/MER formula, shown as a range because published life-stage factors are representative values rather than measurements of your animal β actual needs vary with metabolism and health. Follow your food packβs guide and check with your vet, especially for weight loss, growth or illness.
