Himalayan Dog Chew: 100% natural dog treats made from yak & cow milk with salt & lime juice are easy to digest, lactose-free. Rich in Omega 3, Calcium, Zinc, Vitamin A, Vitamin E & Vitamin D. When peices become small you place them in the microwave for aprox 40 seconds and yak cheese will puff up a puff style treat so your fur-baby can finish this awesome treat. These come as individual sticks and with any item should be consumed while being supervised. Small peices can become a choke hazard.
