Yorkshire Terrier: Age, Food, Lifespan, and Health
Yorkies are toy companions with long silky coats and disproportionately big personalities. Long-lived overall but prone to dental and tracheal issues from small-breed conformation.
Yorkshire Terrier age in human years
Based on the Wang 2019 epigenetic-clock study and the AVMA aging ranges for toy-class dogs. The first year of life equals about 15 human years on its own. The seven-year rule is wrong.
| Dog age | Human-year equivalent | Life stage |
|---|---|---|
| 1 year | 15 | adolescent |
| 2 years | 24 | adult |
| 5 years | 36 | adult |
| 8 years | 48 | mature |
| 10 years | 56 | senior |
| 16 years | 80 | geriatric |
Yorkshire Terrier food portions
Daily food at three sample weights for a spayed or neutered adult on light activity, fed dry kibble at 360 kcal per cup. Uses the NRC veterinary RER formula. Adjust up for working or sport dogs, down for couch dogs.
| Weight | Daily calories | Cups per day |
|---|---|---|
| 4 lb | 175 kcal | 0.5 |
| 5.5 lb | 222 kcal | 0.6 |
| 7 lb | 266 kcal | 0.7 |
At 4 to 7 lb the calculator output is in tablespoons, not cups. A kitchen scale in grams is more accurate than a measuring cup. Quarter-cup overfeeding doubles caloric intake.

How much should I feed my Yorkshire Terrier?
Use the food portion calculator at adjustingstudio.com/paws/tools/food-portion-calculator.

At 4 to 7 lb the calculator output is in tablespoons, not cups. A kitchen scale in grams is more accurate than a measuring cup. Quarter-cup overfeeding doubles caloric intake.
