Unfortunately, determination of kcalories is somewhat more technical than a standardized 225 calories across the board. The basic standard equation that nutritionists use to formulate appropriate kcalorie guidelines is based on a canines RER, or Resting Energy Requirements; where RER(kcal/day)= 30 (body weight in kilograms) + 70. The RER is only valued for resting energy requirements, when other things such as activity, specific breed variants, coat requirements, environmental factors, muscle maintenance, and organ repair are entered into the equation, kcalorie requirements can vary radically. This RER is then multiplied by a specific numerical rate exemplifying the activity level to predict appropriate kcalorie intake that your pup will need for adequate nutrition. So, say you have two five pound yorkies, one is extremely active and the other is very sedate. After deciphering their RER: RER = 30 ( 2.27 kg) + 70 = 138.1, you find that their basic resting requirement is 138.1kcal. For the sedate pup a multiplier of 1.6 is normal so basic kcalorie count would be 220.96 kcals, whereas the active pup would be using a multiplier between 4 and 8 which would put the kcal. count between 552.4 kcals and 1104.8 kcals. So as you can see, there is a drastic difference between these and the standard 250kcalories that you have quoted. My pups are extremely active, and their kcalorie range varies between 325-700 kcalories per day, depending on the exact type of exercises that we are doing. So there it is, somewhat academic and boring, but useful perhaps to someone. | Lordy! Now I need a Tylenol!  Yes, useful though. |
