A neutered 10 kg dog needs about 630 kcal a day. The resting figure is 70 x 10 to the power of 0.75, which is 394 kcal, and a neutered adult is multiplied by 1.6. On a food with 350 kcal per 100 g, that is about 180 g a day.
| Ideal weight | Resting kcal | Daily kcal (x 1.6) |
|---|---|---|
| 3 kg | 160 | 255 |
| 5 kg | 234 | 374 |
| 10 kg | 394 | 630 |
| 20 kg | 662 | 1059 |
| 30 kg | 897 | 1436 |
| 40 kg | 1113 | 1781 |
The weight your dog should be, not always the weight they are. Use the goal weight if they are losing weight.
Calories per 100 g of food. If the packet gives kcal per kg, divide by 10.
Enter your dog's weight and the energy for a day appears here.
This is general information and arithmetic. It is not veterinary advice. Speak with your vet about your own pet.
RER = 70 x (ideal weight in kg) to the power of 0.75
The energy a dog uses at rest. It rises with weight, but not in a straight line, so a dog twice as heavy needs less than twice the energy.
daily kcal = RER x life stage factor
The factors used here: neutered adult 1.6; entire (not desexed) adult 1.8; inactive or prone to weight gain 1.2; losing weight (use the goal weight) 1; puppy under 4 months 3; puppy 4 months to adult 2. Where the guideline gives a range, the page uses the top of it and shows the range.
grams a day = daily kcal / kcal per 100 g x 100
Only worked out when you enter the energy in your dog's food, which is on the packet.
Food is half of the weight equation and exercise is the other half. Find a walker or daycare to keep their weight where it should be.
