How Are Yak Cheese Chews Made? A Step-by-Step Look

Ever wonder how that rock-hard, long-lasting treat your dog loves came to be? Let’s take a peek behind the scenes at how Himalayan yak chews, also called yak cheese chews or Chhurpi, are made using time-tested techniques from the high mountains of Nepal and Tibet. The process combines traditional craftsmanship with modern food safety practices to create one of the most durable natural dog treats on the market. We’ll also cover exactly what yak cheese chews are made of, so you know precisely what’s going into your dog’s treat.

Step 1: Sourcing the milk

The process begins high in the Himalayas, where milk is collected from yaks, Chauris (a yak-cow crossbreed), or grass-fed cows, in the first stage of every yak cheese production process. Traditional Chhurpi uses yak or Chauri milk due to its rich nutrient profile and high protein content. In modern commercial production, including most Himalayan dog chews sold internationally, cow's milk is the primary ingredient, helping meet global demand while maintaining the traditional cheese-making process.

According to the Food and Agriculture Organization (FAO), traditional yak cheesemaking in Himalayan villages begins by gently heating the milk to ensure purity and improve curdling efficiency.

Step 2: Boiling for purity

Freshly collected milk is first boiled to eliminate harmful bacteria. This step not only ensures safety but also prepares the milk for effective curdling. In small mountain villages, milk is boiled in large pots over open fires. In more modern facilities, the process is similar to pasteurization, heated in stainless steel vats under controlled conditions.

Step 3: Curdling the milk

Once the milk is boiled and slightly cooled, it’s time to turn it into curds. A natural acid, such as lime or lemon juice, is added to make the milk curdle. This is one of only two ingredients used in the finished yak chew. This separates the curds (solids) from the whey (liquid). In some traditional methods, a small amount of fermented milk (called a starter culture) is used instead of citrus.

Step 4: Pressing and shaping

The fresh curds are poured into a cloth and pressed to remove moisture. Traditionally, heavy stones are placed on top to press the cheese overnight. In commercial operations, mechanical cheese presses are used for more uniform pressure.

After pressing, the compact cheese blocks are shaped using wooden or steel molds. This gives each piece its distinctive rectangular shape and dense texture.

As documented by the FAO and expanded upon in the National Mission on Himalayan Studies processing manual, drying is one of the most critical steps transforming soft curds into the long-lasting chews we know today.

Step 5: Drying and smoke-curing

Once molded, the cheese is dried and hardened to create its signature chewable toughness. In rural homes, the cheese is hung over kitchen fires and slowly smoked-dried for up to two weeks. The smoke not only dehydrates the cheese but also acts as a natural preservative.

Modern producers dry the blocks in climate-controlled chambers over several days to achieve consistent hardness. Some manufacturers still smoke the chews to retain the traditional flavor and antimicrobial benefits of natural smoke.

Step 6: Cutting and packaging

After the blocks are thoroughly dried, they’re sliced into chewable bars, sorted by size, and carefully packaged to prevent moisture absorption. No additives, no preservatives, just pure, hardened yak cheese made from two simple ingredients: milk and lime.

This shelf-stable treat can last for years when stored properly, making it perfect for export and long-term storage.

From mountain dairy to your dog’s delight, what starts as fresh milk becomes a natural, protein-packed, smoke-dried Himalayan dog chew, all thanks to a centuries-old process rooted in Himalayan tradition. And now you know exactly how it happens.

How We Do It at Yak and Paws

At Yak and Paws, we honor this traditional process while integrating modern technology to ensure consistent quality, enhanced safety, and sustainability.

Building in the Himalayan Embrace: Our 40,000 sq ft state-of-the-art facility, launched in early 2024, is designed for hygienic dairy processing, with an initial capacity of 80,000 liters per day.

Blending Tradition with Modern Quality: We combine centuries-old Himalayan cheese-making techniques with modern food safety standards to produce high-quality dairy products. The chews are crafted using traditional methods while ensuring consistent quality and hygiene for international markets.

Controlled Drying Over Smoke-Curing: Unlike traditional methods that use open fire for smoking, our chews are dried in highly sanitized buildings with controlled microclimate conditions ensuring consistency, safety, and shelf stability without smoke exposure.

Commitment to Safety & Sustainability: All milk products are pasteurized to eliminate harmful bacteria, ensuring safety and purity. Our operations are designed to minimize waste, with whey byproducts repurposed into nutritious livestock feed.

100% Natural, Nothing Else: Our chews are made with just two ingredients milk and lime. No artificial additives, preservatives, or chemicals just pure, natural goodness for your dog.

Yak & Paws Process in 9 Steps: From fresh mountain milk to your pup’s new favorite treat, our Himalayan chews undergo 6 – 12 weeks of maturation depending on each chew’s size and shape in a carefully controlled environment, where we perfect texture, moisture and hardness for the ideal long-lasting bite.

Frequently Asked Questions

Is there a difference between yak cheese chews and regular cow-milk cheese chews?

Yes, though both are used in Himalayan-style chews, yak and Chauri (yak-cow crossbreed) milk is richer in protein and certain fatty acids than standard cow milk. Traditional Chhurpi from the Himalayas uses yak or Chauri milk, which contributes to a denser, harder block. Modern products that use only cow milk can still be high quality but may be slightly softer or differ slightly in flavor.

Why does smoke-drying make the chew last longer, and is it safe?

Smoke-drying removes moisture and creates an antimicrobial environment that naturally preserves the cheese, no artificial preservatives needed. Less moisture means the block is extremely dense, so a dog has to work through solid material rather than something that softens quickly. The smoke itself burns off during drying, leaving behind only the hardened cheese. Some modern producers use controlled indoor drying instead, achieving the same result without open-fire smoke.

What happens to the leftover whey from making these chews?

Whey, the liquid separated during curdling, is a nutritious byproduct rich in proteins and minerals. Responsible producers like Yak & Paws repurpose whey as livestock feed rather than discarding it. This zero-waste approach reduces environmental impact and adds economic value for farming communities. It's one reason Himalayan chews are considered among the more sustainable pet treats available.

Are there any additives or chemicals used in the production process?

Authentic Himalayan cheese chews are made with just two ingredients: milk and a natural acidifying agent such as lime or lemon juice. There are no artificial preservatives, binders, flavors, or chemicals involved. The hardness and shelf stability come entirely from the traditional pressing and drying process.
