Question 1

How accurate is this calculator?

Accepted Answer

It uses the standard veterinary RER × activity factor formula. It's a strong starting point, but body condition score is the gold-standard check — adjust portions every 2 weeks based on whether your dog is gaining, losing, or holding weight.

Question 2

Should I feed once or twice a day?

Accepted Answer

Most adults thrive on two meals. Puppies and seniors typically need three to four smaller meals. Single daily meals raise bloat risk in deep-chested breeds.

Question 3

What if my dog is overweight?

Accepted Answer

Use 80–90% of the maintenance number from this calculator and recheck body condition every 2 weeks. For significant weight loss, ask your vet for a structured plan.

Question 4

How many calories does a 10 kg dog need?

Accepted Answer

Using the standard RER × activity formula, a healthy 10 kg adult typically needs roughly 550–700 kcal per day. Individual dogs vary widely, so use the calculator as a starting point and adjust by body condition.

Question 5

Why does my dog food bag suggest a different amount?

Accepted Answer

Pack guides are averages across many dogs. Your dog's activity, neutering status, age and metabolism change their needs, so adjust the amount to keep them at a healthy body condition.
