Hi Brandie, we feed our guys Fromm's Lamb and Lentil or Fromm's Beef Fritatta. Both of these foods are grain free. The big bag costs $85 without tax, it comes to about $100 Canadian per bag. Fromm's is an American product, so would probably be cheaper in the States. A large bag lasts us for the month, as we have two EB's to feed. This would go twice as far with just one bully. So would be about $50 per month to feed. Fromm's is rated as a 6 Star food, on the dog food ratings on the home page, you want to choose a food that is rated a 4 star or better. There are other good examples of these such as Wellness, Blue Buffalo, Orijen, Arcana, and Go Natural.
