Anco Roe Deer Legs are a single source protein and are hypoallergenic. Deer is a good alternative to more widely available proteins if your dog has common protein allergies/intolerances or food sensitivities. Gently air-dried locking in all natural goodness and flavour, these Roe Deer Legs are perfect for those super keen chewers that require a more durable treat and are perfect for hard gnawing on. Chewing is a great way to stimulate a dog's brain and keep them entertained - and out of trouble. Chewing down on the bone also helps to scrape away unwanted plaque and tartar from their teeth, leaving them healthy and clean.
