Suresh, regarding energy/calorie needs for a 4 yr old dog . . .

No one can really answer this definitively. Breed/size, activity level, health, weather, etc. make a difference. I wouldn’t worry much about it, but feed to ideal body condition and what your dog tells you from energy level/health he needs, and go from there. I’d start with the recommendations on the bag, feeding twice a day, and then adjust. Good luck.
