THE ORIGINAL SINGLE INGREDIENT PET TREAT NO ADDITIVES, FILLERS, COLORING OR PRESERVATIVES. Pet owners and in particular dog trainers, have discovered Benny Bully's Liver Chops as a nutritious, pure and natural alternative to traditional pet treats. We developed an innovative cutting and drying process, as an alternative to conventional food preservatives, making Benny Bullys one of the few "no chemicals added" treats on the market today. Made from pure natural beef livers, we sliced and specially sized each piece to provide easy feeding, maximum palatability and attract the most hard to please pets. Benny Bullys pure natural fillets of beef liver, offer your pet a full true flavour.
