So very recently we have changed the food that we are using at Angel Pawz. With the Buffalo Blue we have been having many digestive problems with the dogs and the puppies. The food we are now using is by Nutro called Natural Choice, it is the Chicken, brown rice, and oatmeal formula. It is in a mint green bag both the puppy and adult formula. A heaping 1/3 scoop three times a day for puppies, and twice a day for adults. Switching from Puppy to Adult formula starts at one year old. This food can be found at petsmart or petco. If you have a dog or puppy already on the Blue Buffalo, you DO NOT have to switch if you are comfortable with the BLUE, and if you do decide to switch formulas, you NEED to mix the formula you are on with the new food, half and half, for a week. If you do not mix the two your dog WILL have digestive issues.
