TL;DR: What are Cold-Dried™ Bully Sticks?
Cold-Dried™ Bully Sticks are the first and only bully sticks made with proprietary low-temperature drying technology. Up to 97% crude protein, 1% fat, 100% natural single ingredient (grass-fed beef pizzle). Denser and firmer than standard bully sticks, designed for medium-to-strong chewers who finish regular sticks too fast. Fully digestible, odor-free, exclusive to Natural Farm.
Standard bully sticks are great. But if your dog finishes one before you've even sat down, you already know the problem: not enough chew time, money spent too fast, and a dog that's bored again.
Cold-Dried™ Bully Sticks were built to solve this. Same 100% natural single ingredient (grass-fed beef pizzle), same full digestibility, same odor-free experience. But denser, firmer, and significantly longer-lasting because of how they're dried. This guide covers everything: the technology behind them, full nutritional specs, sizing, how to introduce them to your dog, real customer reviews, and how they compare to every other Natural Farm bully stick.

What Is Cold-Dried™ Technology?
Cold-Dried™ is Natural Farm's proprietary low-temperature drying process, developed with AI. It slowly removes moisture from 100% grass-fed beef pizzle at controlled low temperatures, preserving the natural protein structure while creating a denser, firmer chew.
The problem it solves: for years, dog owners had to choose between nutrient preservation (freeze-dried, but soft and short-lasting) or durability (standard dehydrated, but loses some nutrients to heat). Cold-Dried™ eliminates that trade-off. Low enough temperatures to preserve protein chains intact. Slow enough process to create structural density without porosity. The result is the highest-protein, densest bully stick on the market.
🔑 Why it matters: No other brand offers Cold-Dried™ technology. The process is proprietary to Natural Farm. You won't find this drying method, this protein concentration, or this texture density anywhere else. For a detailed technical comparison with freeze-dried and standard dehydrated, see Freeze-Dried Bully Sticks: What to Know.
Full Specs + Guaranteed Analysis
Every dog treat sold in the US must display a guaranteed analysis per AAFCO standards. Here are the Cold-Dried™ numbers:
What does 97% protein mean in practice? Nearly 20g of pure protein per 6" stick. That's comparable to a serving of chicken breast, delivered in a format that also cleans teeth, reduces anxiety, and keeps your dog engaged significantly longer than standard sticks. Standard bully sticks sit at ~93%. Freeze-dried at ~62%. Cold-Dried™ pushes beyond both because the low-temperature process preserves protein chains intact rather than breaking them down.
At just 1% fat, Cold-Dried™ is also the leanest bully stick available. For dogs on low-fat or weight management diets, this matters. The calories (~90-95 per 6" stick) should be factored into your dog's daily intake. Full calorie breakdown by bully stick size.
Sizing Guide: Is Cold-Dried™ Right for Your Dog?
Cold-Dried™ is designed for a specific segment of dogs. It's not for everyone, and we'd rather you pick the right product than the wrong one.
🔑 The simple test: Give your dog a 12" Standard Bully Stick. If it disappears quickly, Cold-Dried™ is the upgrade. If your dog demolishes it almost instantly, skip to Power Chews. If it lasts a long session, standard is the right fit.
How to Introduce Cold-Dried™ to Your Dog
Cold-Dried™ Bully Sticks are denser than standard. Even experienced chewers should start with shorter sessions to let their jaw and stomach adjust.
⚠️ If your dog has never had a bully stick before: Start with a standard 6" stick, not Cold-Dried™. The high protein concentration (~97%) can cause digestive upset in dogs not accustomed to protein-rich chews. Introduce standard first, then upgrade to Cold-Dried™ once their system is adjusted.

What Dog Owners Are Saying
Cold-Dried™ vs Other Natural Farm Bully Sticks
Natural Farm makes several types of bully sticks. Here's how Cold-Dried™ fits in the lineup:
| Feature | Cold-Dried™ | Standard | Extra Thick | Braided | Power Chews |
|---|---|---|---|---|---|
| Protein | Up to 97% | ~93% | ~93% | ~86% | Varies |
| Fat | 1% | ~3% | ~3% | ~5% | ~3% |
| Chew Time | Extended | Moderate | Moderate-Long | Long | Longest |
| Texture | Dense, firm | Standard | Thick | Woven layers | Dual-layer |
| Best For | Med-strong chewers | All dogs | Large breeds | Extended time | Power chewers |
Cold-Dried™ sits between standard bully sticks and Power Chews in durability. It's the protein champion of the lineup. If your priority is maximum nutrition per chew, Cold-Dried™ wins. If your priority is maximum durability for extreme chewers, Power Chews win. If you want the best all-around value, 12" Standard is still our best seller for a reason.

Frequently Asked Questions
How long do Cold-Dried™ Bully Sticks last?
How long a Cold-Dried™ Bully Stick lasts depends on your dog's size, jaw strength, and chewing style. Most dogs get significantly more chew time compared to a standard stick of the same size. The dense texture means the stick breaks down more slowly, extending engagement per session. Full durability ranking.
How many calories are in a Cold-Dried™ Bully Stick?
Approximately 90-95 calories per 6" stick. Slightly higher than standard (~88 cal) because the denser texture concentrates more material per inch. But because Cold-Dried™ lasts significantly longer per session, it delivers fewer calories per minute of chewing than any other bully stick format. Calorie guide.
Can puppies have Cold-Dried™ Bully Sticks?
Not recommended for puppies under 6 months. The dense texture is designed for dogs with fully developed adult teeth and medium-to-strong jaw strength. Puppies 6+ months can try Cold-Dried™ with short supervised sessions to start. For younger puppies, Pixie or Thin Bully Sticks are gentler. Puppy guide.
Are Cold-Dried™ Bully Sticks better than regular bully sticks?
Better depends on your dog. Cold-Dried™ has higher protein (97% vs 93%), lower fat (1% vs 3%), denser texture, and longer chew time. But standard bully sticks are perfectly good for dogs who don't need the extra density. Cold-Dried™ is an upgrade for dogs that finish standard sticks too quickly.
What is the shelf life of Cold-Dried™ Bully Sticks?
Unopened, 2-3 years in a cool, dry place away from direct sunlight. Once your dog starts chewing one, seal it in a ziplock bag or airtight container, refrigerate, and use within a week. Do bully sticks go bad?
Are Cold-Dried™ Bully Sticks fully digestible?
Yes. 100%. Same 100% natural single ingredient as every bully stick (beef pizzle), just processed differently. They break down completely in the stomach within hours. Unlike rawhide, which cannot be digested. Are bully sticks safe?
Do Cold-Dried™ Bully Sticks smell?
No. The low-temperature process controls moisture removal without producing the volatile compounds that cause strong odors in other processing methods. Genuinely odor-free. Couch, bed, car.
Cold-Dried™ vs Power Chews: which lasts longer?
Power Chews last significantly longer. They use a completely different design: a durable beef cheek outer layer wrapped around a beef pizzle core. Cold-Dried™ wins on protein density (97% vs varies). Choose Cold-Dried™ for max nutrition, Power Chews for max durability. Chews for power chewers.
Are Cold-Dried™ Bully Sticks worth the price?
If your dog finishes standard sticks quickly, yes. Cold-Dried™ delivers roughly double the chew time of standard at a modest price increase. That means fewer sticks consumed per week, which often makes them cheaper over time despite the higher per-unit cost.
Where can I buy Cold-Dried™ Bully Sticks?
Exclusive to Natural Farm. Available on naturalfarmpet.com and through Amazon. No other brand offers Cold-Dried™ technology because the process is proprietary.
