How much to feed a puppy

Puppies need about 3 times the calories of a resting dog of the same weight until they’re 16 weeks old, then about twice as much until they’re fully grown. Vets work it out with a standard formula, and that’s what this calculator uses.

Use the result to check the feeding guide on the pack. If the two disagree a lot, start in between and go by your puppy’s shape:

How many meals a day

Under 12 weeks4 meals
12 weeks to 6 months3 meals
6 months and over2 meals

Small breeds are fully grown at about 12 months, big breeds at 18 months or more. Switch to adult food then.

Thinking about fresh food?

Fresh cooked food is portioned for your dog’s weight and delivered. It costs more than dry food, so check the monthly price above first.

Questions

How do I change my puppy’s food?

Slowly, over 7 to 10 days. Mix a little of the new food into the old, and add more each day. Keep to the breeder’s food for the first couple of weeks after you bring your puppy home.

Do treats count?

Yes. Keep treats under a tenth of the day’s calories, and use part of their daily food as training treats.

Should I weigh the food?

Yes. Cups and scoops can be out by 20% or more. Kitchen scales are the easy way to get it right.
