You may have heard that treats should make up no more than 10 percent of your dog’s calories. But if you don’t know how many calories your dog should be consuming in the first place, that advice isn’t so handy-dandy. Fortunately, there’s a formula for the right number of daily calories overall, at least if your dog weighs between 5 and 55 pounds: 30 x ideal weight (in kilograms) + 70.
If converting kilograms to pounds is not your thing, see the chart below. It gives numbers 
for dogs who weigh more than 55 pounds, too. Just keep in mind that the chart’s numbers are estimates. They only account for a modicum of physical activity, for instance. If your dog is very active, he may require more calories than the number listed.
