Hi all. Quick question............... is there a reduced calorie dry dog food? My boy has been eating Purina Pro Plan dry kibble but I think I have been giving him too much of it (too many calories) He is almost 2 years old and weights 40 lbs. I had been feeding him 1 cup with about 3 tablespoons of pure pumpkin in the morning and again in the evening. He really doesn't get too many treats and no people food. Should I just cut the Purina Pro Plan in half or is there another food you would recommend? Too much pumpkin? He loves the pumpkin.
