Hmmm....why are you cutting the fat off of the food? Are you feeding feedlot beef or organic beef? I only feed organic beef that is grass-fed and free-range. Grass-fed and free-range beef does not contain excess fat, but a normal amount of fat for the prey species. If you are feeding feedlot beef, I can see cutting off excess fat, if that is your dog's main source of nutrition. I really suggest that you switch to organic beef that is grass fed and free range. It is much better for your dog. I really don't suggest you cut the fat out of meat. Dogs need fat. Using it as a treat really isn't necessary. Just leave it on. I use chunks of chicken, chicken feet, turkey chunks, turkey liver, turkey hearts, and apple pieces as treats. But, I feed almost exclussively chicken and turkey. Odin just doesn't care for rabbit, beef, lamb, etc. He likes his poultry. lol Another cut up carrots or pieces of butternut squash. Odin also like raw chicken pieces rolled in flaxseed as a training treat. I'll also give him a raw egg if he's been a good boy, like after a walk or when getting back from the veterinarian. Supplemental clay also works as a treat. You can wet it and roll it into a ball. Odin loves it!
