The 6" bully stick is BSD's best-selling size and, in most metrics, the most versatile single chew format in the lineup. It serves small dogs as a primary full-session enrichment chew, medium dogs as the daily rotation format, and large dogs as the shorter-session rotation component when a brief enrichment period is the goal rather than the primary long session. With approximately 90 million dogs in US households spanning every size from under 5 lbs to over 150 lbs, and the 6" format serving dogs from 10 lbs through 65 lbs as appropriate depending on the use case, the 6" covers more of that population with a single format than any other length BSD carries. It is the format that new bully stick customers start with regardless of dog size (to establish chewing behavior and confirm product acceptance before purchasing larger quantities), the format that experienced small dog owners receive most frequently on autoship, and the training-adjacent reward format that many medium and large dog owners use alongside their primary 9" or 12" sticks.
Why the 6" is the correct starting format for any dog trying bully sticks for the first time: Regardless of dog size, the first bully stick introduction should use the 6" format. For a 70 lb Lab, the 6" is not the correct permanent primary format — the 12" will be — but the 6" introduction serves an important function: it establishes that the dog engages with and safely chews bully sticks before committing to larger quantities of a 12" format. Most dogs accept bully sticks immediately on first presentation; some dogs with limited dried meat chew experience require 1–3 sessions to learn the category before engaging confidently. The 6" introduction costs less if the dog turns out to need an adjustment period, and confirms the correct upgrade path (if the 6" is consumed in under 12 minutes by a large dog, the 12" is confirmed as the appropriate primary format). Start with 6", time the session, and use that data to select the correct permanent format.
The 6" as Primary Format — Who Uses It Daily
Small dogs under 20 lbs — The 6" is the primary daily enrichment format for small breed dogs including Chihuahuas, Yorkshire Terriers, Maltese, Toy Poodles, Shih Tzus, Pomeranians, and small Dachshunds. Sessions run 22–38 minutes for light-to-moderate small breed chewers — the full enrichment session duration at a size and caloric contribution appropriate for small body weight management.
Medium dogs 20–40 lbs — Beagles, Cocker Spaniels, Cavalier King Charles Spaniels, French Bulldogs, Miniature Schnauzers, Basset Hounds, and medium-weight Dachshunds all use the 6" as their primary daily format producing 20–32 minute sessions appropriate for their size.
Large dogs as rotation component — Labs, Goldens, and Shepherds primarily receiving 12" sticks can use 6" sticks as the short-session rotation format for days when a brief treat is the goal or when the primary enrichment has already been provided through exercise or other activity.
Multi-dog households — The 6" at competitive per-stick pricing is the bulk purchase format for multi-dog households with dogs of mixed sizes, where a 6" works for all dogs at least as a minimum appropriate chew.

Frequently Asked Questions
Yes — bully sticks are appropriate for dogs of all sizes from the appropriate format. The 6" bully stick uses the same single-ingredient dried beef pizzle as the 12" and 36" formats; the length is the only variable. Small dogs do not need a special formulation — they need the right length for their jaw size and chewing capacity. The 6" is sized appropriately for dogs under 40 lbs as a full primary enrichment chew. For very small dogs under 10 lbs, the 4-5" format may be more size-appropriate given that a 6" stick may be geometrically awkward for a dog whose entire body is shorter than the stick length. Observe how your small dog positions and holds the stick in the first session — if they cannot establish a comfortable grip and advance progressively, move to the 4-5" format.
Single-ingredient 6" bully sticks are appropriate for Cavaliers with mitral valve disease provided the stick fits within the overall dietary management framework your veterinarian has established. The key considerations: bully sticks are single-ingredient beef pizzle with no added sodium, no artificial preservatives, and full ingredient transparency — appropriate for Cavaliers where ingredient monitoring is required. The caloric contribution (~80–120 calories per 6" stick) should be factored into daily intake. The physical activity of chewing itself (moderate jaw exercise) is not a cardiac concern at the level of a bully stick session; the endorphin and cortisol effects of sustained chewing are generally positive for stress-related cardiac considerations. Confirm with your veterinarian that beef is permitted in the cardiac dietary protocol and that the caloric contribution fits within the daily intake plan. If your Cavalier is on a sodium-restricted cardiac diet, confirm that the natural sodium content of dried beef pizzle is within the daily allowance — naturally dried beef products contain some natural sodium from the meat tissue, so this is worth confirming rather than assuming.
