I wouldn’t worry too much about counting calories. Right now, your dog’s telling you he’s not satisfied after a meal. High quality kibble or whatever your own formula is must have high fiber, vitamins & minerals. The wrong mix will make him beg for more fatty treats. The first five ingredients listed are very imported, good meats. Meals and treats should be at the same time everyday, no extras from other people. Google “beagle weight chart”, follow the images to see where he’s at visually in weight then adjust the amount of food per day vs amount of exercise and satisfaction. You will eventually find the correct amount visually, not by calories. Exercise is a must and playtime with a toy or bully bone keeps his mind off of scrounging.
