Daily calories and grams for a 5 kg (11.0 lb) dog
Resting energy for 5.0 kg is 234 kcal (70 × 5.00.75). Multiply by the factor for the life stage to get the day's energy, then divide by the food's kcal per gram.
| Life stage | kcal a day | g at 3,400 kcal/kg | g at 3,600 kcal/kg | g at 3,800 kcal/kg |
|---|---|---|---|---|
| Neutered adult | 374 | 110 | 104 | 99 |
| Intact adult | 421 | 124 | 117 | 111 |
| Inactive or prone to weight gain | 328 | 96 | 91 | 86 |
| Puppy under 4 months | 702 | 207 | 195 | 185 |
| Puppy 4 months to adult | 468 | 138 | 130 | 123 |
These are averages from the Merck/WSAVA energy factors. Your dog may need 10 to 20% more or less. Check the energy on your own food's label and use the calculator below.
Meals, treats, water and cost
| Two meals a day (neutered adult) | 52 g each |
|---|---|
| Three meals a day | 35 g each |
| Treat allowance (10% of calories) | 37 kcal: 12 pieces of 3 kcal, or 1.0 of 38 kcal |
| Water (about 50 mL per kg) | 250 mL (range 200 to 300); call the vet above 500 mL |
| Dry food as a share of body weight | 2.1% a day |
| Calories per kilogram of body weight | 74.9 kcal per kg |
Monthly food cost at example prices
Cost = grams a day × 30 ÷ 1,000 × price per kg. The prices are examples; use your own.
| Price per kg | 3.00 | 4.00 | 5.00 | 6.00 |
|---|---|---|---|---|
| Dry food, 3,600 kcal/kg | 9.36 | 12.48 | 15.60 | 18.72 |
How long a bag lasts

A sample day for a 5 kg (11.0 lb) dog
One way to lay out a neutered adult's day on a 3,600 kcal/kg dry food, with treats counted inside the total.
| Time | What | Amount |
|---|---|---|
| Morning | Meal | 47 g |
| During the day | Treats and training rewards (counted) | 37 kcal |
| Evening | Meal | 47 g |
| All day | Fresh water (about 250 mL) | Always available |
Meals are smaller than the table above because the treat allowance of 37 kcal is taken out of the day's 374 kcal: 337 kcal of meals is 94 g.
If you feed wet and dry together
Split the calories, not the grams. This uses a wet food of 1,000 kcal/kg and a dry food of 3,600 kcal/kg for a neutered adult needing 374 kcal.
| Share of calories from wet food | Wet food | Dry food |
|---|---|---|
| 25% | 94 g | 78 g |
| 50% | 187 g | 52 g |
| 75% | 281 g | 26 g |
Do not add wet food on top of the full dry amount: that doubles the calories it replaces.

If your 5 kg dog is overweight
Using the rule that each body-condition point above 5 (of 9) is about 10% over ideal weight, here is what a weight-loss plan could look like. The calorie target is 1.0 times resting energy at the goal weight, and the pace is 1 to 2% of body weight a week (AAHA 2014). Your vet should confirm the goal and the plan.
| Body condition | Goal weight | kcal a day | g of 3,600 kcal/kg food | Weeks at 2% to 1% a week |
|---|---|---|---|---|
| 6 of 9 | 4.5 kg (10.0 lb) | 218 | 61 | 5 to 10 |
| 7 of 9 | 4.2 kg (9.2 lb) | 204 | 57 | 10 to 19 |
| 8 of 9 | 3.8 kg (8.5 lb) | 192 | 53 | 13 to 27 |

Age and life stage if 5 kg (11.0 lb) is your dog's adult weight
Age charts group dogs by adult size. At 5 kg (11.0 lb) the size group is small, which adds 4 human years for each dog year after the second.
| Dog's age | Human years (size chart) | Human years (epigenetic formula) |
|---|---|---|
| 1 year | 15.0 | 31.0 |
| 3 years | 28.0 | 48.6 |
| 5 years | 36.0 | 56.8 |
| 8 years | 48.0 | 64.3 |
| 10 years | 56.0 | 67.8 |
| 12 years | 64.0 | 70.8 |
Why a dog twice as heavy does not eat twice as much
Energy needs rise with body weight to the power 0.75, not in a straight line. Moving from 5 kg to 6 kg is a 20% weight increase but only about 15% more calories. At 5 kg (11.0 lb), the neutered figure is 74.9 kcal per kg of body weight.
What changes your dog's number
- Neutering and activity. The table shows a 10 to 30% spread between stages.
- The food. A richer food means fewer grams for the same calories.
- Treats. They count within the daily total.
- Weight trend. Weigh monthly, score body condition and adjust by about 10%.
- Health. A pet on a veterinary diet or with a health condition should follow the vet's plan.
Frequently asked questions
How much should a 5 kg (11.0 lb) dog eat a day?
A neutered adult of 5 kg (11.0 lb) needs about 374 kcal a day. On a 3,600 kcal/kg dry food that is about 104 g. Intact and inactive dogs need 421 and 328 kcal.
How many meals a day for a 5 kg dog?

A common weight-loss target is 1.0 times resting energy at the goal weight: about 204 kcal a day, or 57 g of a 3,600 kcal/kg food. At 1 to 2% of body weight a week that takes about 10 to 19 weeks. Your vet should confirm the goal and the plan.
