PETMEX beef liver is a natural, aromatic chew that works perfectly as a healthy treat for dogs of all ages. Dried liver is an excellent source of iron and B vitamins, which support immunity, metabolism, and the dog’s overall condition. The product is 100% natural, free from preservatives and dyes, made from a single source of protein – beef. Its intense taste and smell make even picky dogs eager to reach for it. Beef liver has moderate hardness – it satisfies the need to bite and chew, supports oral hygiene, and is suitable for both younger and older dogs. It also works great as part of a BARF diet.
