Keep your canine companion happily occupied with Himalayan Pet Supply Himalayan Dog Chew Original Yak Cheese Dog Chews. If you were a cheese-lovin' dog, you'd think the best kind of cheese is the kind it takes hours to eat, too! These dog treats are paw-fect for dogs under 65-pounds. They are made from 100% yak and cow’s milk along with salt and lime juice. They can take hours of chewing to soften enough to scrape a tasty bite off. These treats are great for removing plaque and promoting oral health, too!
