How Much Should a Yorkie Eat?

There is no single correct number of calories for every Yorkshire Terrier, and any guide that promises one is overselling. What we can do is give you a defensible starting estimate, explain where it comes from, and show you how to adjust it using your own dog's body rather than a chart.

Where the calorie estimate comes from

Veterinary nutrition guidance builds a daily energy estimate in two steps. First, resting energy requirement (RER) — the calories needed at rest — is estimated from body weight in kilograms using the formula RER = 70 × (body weight in kg) raised to the power of 0.75. Then that resting figure is multiplied by a maintenance factor that reflects life stage, neuter status, and activity.

For a 2.3 kg (about 5 lb) Yorkie, RER works out to roughly 130 kcal. Multiplying by a typical maintenance factor for a neutered, moderately active adult (commonly in the 1.2–1.6 range) lands you somewhere around 150–210 kcal per day. That is why you will see a range rather than a precise figure — the maintenance factor genuinely differs from dog to dog.

Maintenance factors that shift the number

• Intact (not spayed/neutered) adults tend to need slightly more than neutered adults.
• Very active or working dogs need more; couch-loving companions need less.
• Growing puppies need substantially more per pound than adults (see our puppy schedule guide).
• Older, less active seniors often need fewer calories, and are prone to creeping weight gain.
• Overweight dogs on a vet-directed plan are fed to a target weight, not their current weight.

Judge the dog, not the scale alone

Because a Yorkie is so small, a bathroom-style scale rarely has the resolution to catch meaningful changes. Body condition scoring is more useful day to day. In a dog at a healthy weight you should be able to feel the ribs easily under a thin layer of fat without pressing hard, see a visible waist from above, and see a tucked-up abdomen from the side.

If the ribs are hard to feel and the waist disappears, the daily amount is too high. If ribs, spine, and hip bones are prominent and sharp, it is too low. Adjust by a small percentage at a time and reassess over a couple of weeks.

Turning calories into a portion

Every complete dog food lists a calorie content statement — usually kilocalories per cup and per kilogram — on the label. Divide your dog's daily calorie target by the food's kcal-per-gram figure to get grams per day, then split that across meals. A gram scale is far more accurate than a measuring cup for a dog this size, where a small scooping error can be a large fraction of the day's food.

This article is educational and not a substitute for individualized veterinary advice. If your Yorkie has a medical condition, is losing or gaining weight unexpectedly, or you are unsure about a healthy target, your veterinarian can set a specific plan.
