I've been thinking for a while now that feeding the dogs would be so much easier if I know how many calories my dogs needed. The conventional wisdom of "what the bag lists is always too much" didn't work for me because my Aussie would be getting more than what was on the bag and still be super skinny or even losing weight. Lyla, however, the Corgi, does have to be watched closely. Even though she is not a big eater, she seems to get chubby a lot faster than Sky. I thought about how I determined my diet. When I plan out my meals, I take note of how many calories I need to consume that day to maintain or lose weight and factor in exercising, extra snacks, etc. It would only make sense to do this for my dogs too!
And.... I finally did find a dog calorie calculator!! (

There are two calculators on this site, I liked the second one closer to the bottom of the page better. It seemed to be more accurate in terms of portion sizes. I then looked on the dogs' food bag and got the kcal/cup content and the calorie content of their bedtime biscuits (you can also find this information on the website of the dog food company that makes your food). So, as an example, Sky is 25 pounds and should be getting about 681 calories/day. He gets one biscuit a day @ 113 calories. The leaves him with 568 calories/day. I divided that by the caloric content of his food which is 457 cal/cup. According to that he should be getting about 1 1/4 cups of food a day to maintain 25 lbs at his activity level.
I really like having a number to base their diet on. Even though things will still have to be adjusted from time to time, it gives me a good base to work with. Now on a training day, I know how much to decrease their food by to make up for those training treats. I hope this is also helpful to those of your here at mycorgi.com!
