Grass-fed bully sticks are single-ingredient beef chews, but stick thickness, pack format, and ingredient details vary. Natural Farm is best for buyers who want a weight-based pack; Big Lu offers a fixed 12-count pack; WOOF emphasizes options for different dog sizes; BRUTUS & BARNABY’s thick sticks suit powerful chewers; and its skinny sticks are designed for smaller mouths. Compare the listed features below, and supervise your dog whenever you offer a chew.
| Product | Best For | Pack Format |
|---|---|---|
| Natural Farm | Buyers who prefer a weight-based pack | 12 ounces; stick count varies |
| Big Lu | A fixed-count supply | 12 sticks, 6 inches |
| WOOF | Enrichment and a range of dog sizes | 10 sticks, 6 inches |
| BRUTUS & BARNABY Thick | Dogs that need a denser chew | 12 sticks, 6 inches |
| BRUTUS & BARNABY Skinny | Small dogs and gentler jaws | 16 sticks, 6 inches |
Natural Farm Weight-Based Bully Sticks

Natural Farm’s 6-inch sticks are made from 100% grass-fed Brazilian beef, according to the product details. The listing describes them as free of additives and preservatives and promotes them for chewing, mental stimulation, and dental cleaning.
Best for: Buyers who prioritize a set total weight over an exact stick count. The bag contains 12 ounces, with approximately 11 to 14 sticks, so the quantity can vary. That makes it less suitable if you need a predictable number of individual chews. The listing describes these chews as odor-free and fully digestible.
Big Lu 12-Count Grass-Fed Chews

Big Lu provides twelve 6-inch standard bully sticks. The brand says each chew is made from 100% grass-fed beef pizzle, with no fillers, artificial preservatives, hormones, chemicals, or unnecessary ingredients. The listing presents them as a way to occupy dogs or reward good behavior.
Best for: Households that want a fixed-count pack and a straightforward ingredient description. Choose this if knowing the number of sticks matters more than choosing a thick or skinny style. The listing identifies these as standard sticks, so they may not be the right shape or chew challenge for every dog.
WOOF 6-Inch Enrichment Chews

WOOF’s pack contains ten 6-inch chews. The listing describes them as made with free-range, grass-fed beef and natural, protein-rich ingredients. It positions the sticks as enrichment treats for puppies and dogs of small, medium, and large sizes.
Best for: Buyers looking for a 10-count pack for a regular enrichment routine. The listing emphasizes broad size suitability, but it does not specify a skinny or extra-thick diameter in the provided details. Check the individual chew’s size against your dog’s jaw and chewing style rather than relying on a general size label alone.
BRUTUS & BARNABY Thick Bully Sticks

These 6-inch sticks come in a 12-count pack and are described as extra thick and dense. The listed ingredient is 100% grass-fed beef pizzle, with no fillers, hormones, grain, or artificial preservatives. The brand says a chemical-free cleaning process removes odor without bleach or harsh rinses.
Best for: Dogs whose owners are seeking a denser chew, including determined chewers. Thickness can make a chew more challenging, but it does not guarantee a particular chew duration. Avoid this style if your dog has a small mouth or struggles with thicker chews; the listing does not provide a specific diameter.
BRUTUS & BARNABY Skinny Bully Sticks

This pack contains sixteen 6-inch skinny sticks. The product details describe a single ingredient—grass-fed South American beef pizzle—with no fillers, artificial preservatives, added hormones, or grain. The narrower style is intended for small dogs, puppies, and senior dogs with gentler jaws; the listing also describes an air-dried process intended to reduce odor.
Best for: Owners seeking a narrower chew rather than a standard or thick stick. It may be a better fit when a conventional bully stick seems too thick, though puppies and senior dogs still need a chew suited to their individual teeth and chewing habits. Its skinny shape may be less suitable for dogs that need a more substantial chew.
Buying Guide: How to Choose Grass-Fed Bully Sticks
Should you choose a standard, thick, or skinny stick?
Match the chew’s diameter to your dog’s mouth, teeth, and chewing behavior. Skinny sticks are specifically positioned for smaller mouths and gentler jaws. Thick sticks are marketed for more determined chewers. Standard sticks offer a middle-ground format, but product descriptions may not give exact diameters. When size is unclear, check the product listing and choose a chew your dog can handle comfortably.
Does pack count or pack weight matter more?
Count-based packs make it easier to know how many chews are included. A weight-based pack may contain different numbers of sticks from bag to bag: Natural Farm lists 12 ounces and approximately 11 to 14 sticks. If you plan treats by quantity, compare the listed count. If total product weight matters more, a weight-based pack may suit your needs.
What should you check in the ingredients?
Look for a clear ingredient statement and compare it with your dog’s dietary needs. Several products here specify beef pizzle as the sole ingredient, while WOOF’s provided description says natural, protein-rich ingredients and grass-fed beef without explicitly stating a single ingredient. Grass-fed labeling does not establish that a chew is appropriate for every dog.
How should you offer a bully stick?
Give chews under supervision and consider your dog’s chewing habits. Take the chew away if it becomes small enough to swallow whole or if it is damaged. Follow the product’s serving guidance and ask a veterinarian about chews if your dog has dental concerns, dietary restrictions, or a history of swallowing treats quickly.
