YAKERS are 100% Natural Dog Chews made with Himalayan Yak Milk Perfect for both tough chewers and gentle chewers, YAKERS dog chews are a low-fat (5.2%) treat for dogs over the age of 4 months. The vegetarian treats are also rich in calcium and protein, gluten and preservative free. 100% natural, YAKERS dog chews are great for your dog’s oral hygiene, helping remove plaque during the chewing process. The hard texture means dogs need to soften and work at the treat potentially for hours before they’re rewarded with small pieces to chew off. YAKERS dog chews are made in the hills of the Himalayas using a mix of skimmed Yak and Cow milk. A very small amount of lime juice and salt is added to harden the milk, which is then compressed into blocks and traditionally smoke dried for 28 days to give the cheese chews their unique flavour.
