Most adult dogs do best with two meals, about 8-12 hours apart.
Check the back of the bag or can. Dry kibble is usually 300-500 kcal/cup; wet food is typically 70-130 kcal/100 g.
The exact number from your pet food label. Using a typical dry-kibble default if left blank.

Your dog needs about 692 kcal per day.

  • The resting baseline (RER) is 433 kcal/day. Multiplied by 1.6 for "spayed or neutered adult", your dog needs about 692 kcal/day in total.
  • Up to 69 kcal may come from treats (10% of the total), leaving 623 kcal - undefined - for each meal.
  • These numbers are a starting point. Weigh your dog every 2-4 weeks and adjust the portion by 10-15% if weight changes more than 2% in either direction.

Next stepPair this with a body-condition score assessment (1-9 scale) to fine-tune the portion - you should be able to feel ribs easily but not see them at a healthy score of 4-5.
