Bully Stick Calories: Chart by Length and Dog Weight

By INVIROX Training Team · Published 2026-10-22 · 9 min read

How many calories are in a bully stick?

Most owners think of a bully stick as a chew, not a meal, and that is where the calories slip through. A bully stick is dried beef muscle, almost all protein, and it carries real energy.

The best data comes from a study by Freeman, Janecko and Weese, published in the Canadian Veterinary Journal in 2013. The researchers measured 26 bully sticks bought from retailers in the United States and Canada. Calories ranged from 9 to 22 per inch, with an average of 15 per inch. According to Tufts University's summary of the study, an average 6-inch stick came to about 88 calories.

The same study found something more useful for owners: calories per gram were very consistent, at about 2.96 to 3.07 calories per gram. The big spread per inch comes from thickness and density, not from the meat itself. A thick, heavy stick simply has more beef in each inch than a thin one.

Bully stick calories by length: the chart

This chart applies the measured range of 9 to 22 calories per inch, and the average of 15, to the most common stick lengths. Thin sticks sit near the low column, thick and jumbo sticks near the high column.

The average column lines up with the published figures. Tufts reported about 88 calories for an average 6-inch stick, and veterinary nutritionists Gaylord and Raditic, writing in Today's Veterinary Practice, give about 120 calories for an 8-inch stick.

If you only remember one thing from this page, make it the weighing rule. Length tells you roughly where a stick sits. Weight tells you far more precisely.

What share of your dog's daily calories is that?

The same stick is a small snack for a big dog and a large meal for a small one. Two published sources give us firm reference points. Tufts University reported that an 88-calorie stick is about 30% of a 10 lb dog's daily calories and about 9% of a 50 lb dog's. Today's Veterinary Practice put a 120-calorie stick at 11.8% of a 50 lb dog's daily intake.

Those figures imply daily needs of about 290 calories for a 10 lb dog and about 980 to 1,020 for a 50 lb dog. For the other weights in the table we drew a smooth curve through those two sourced points. It follows the pattern they show, where five times the body weight needs about 3.3 times the calories, so calories rise a little more slowly than weight. Those rows are labelled approximate.

Treat these as a starting point. Real needs vary a lot with age, activity, neuter status and breed, and a lazy 50 lb dog can need far less than a working one. Your vet can give you your own dog's daily target, and that number always beats a chart.

The 10% treat rule, in bully stick inches

Veterinary nutritionists recommend that treats and chews together make up no more than 10% of a dog's daily calories, as Gaylord and Raditic explain in Today's Veterinary Practice. The other 90% should come from a complete and balanced diet. Here is what that 10% looks like when you translate it into an average bully stick at 15 calories per inch.

Read that table as chewing time, not as a cutting guide. A 10 lb dog's budget is about two inches of stick, but a two-inch piece is exactly the size that gets swallowed. The safe way to stay inside the budget is to give a longer stick for a short, timed session, then put it away in a sealed bag for another day.

It also shows why the treat budget is shared. If a bully stick uses the whole 10%, training treats, table scraps and dental chews that day push the total over. On chew days, use smaller training treats or part of the dog's own kibble as rewards.

How to trim meals on chew days

You do not need to stop bully sticks to keep a dog lean. You just need to make room for them. This takes about two minutes the first time and becomes automatic.

1. Find the calories in your dog's food. The bag lists calories per cup or per can, usually near the feeding guide.
2. Estimate the stick's calories. Weigh it and multiply by 3, or use the length chart above.
3. Decide how much of the stick your dog will chew today. A stick spread over three sessions counts as a third per session.
4. Subtract those calories from the day's food. Take the amount off the evening meal, so the dog still gets a normal breakfast.
5. Weigh your dog every two to four weeks and adjust if the weight creeps up.

A worked example: a 50 lb dog eats a food listed at 350 calories per cup, and gets an average 6-inch stick of about 90 calories in one day. That is about a quarter of a cup, so the evening meal drops by a quarter cup. If the stick is spread across three days, the trim is about a third of that each day, roughly a tablespoon or two.

Why it matters: most dogs are already over their ideal weight

Counting chew calories can feel fussy until you see the numbers. In the Association for Pet Obesity Prevention's 2022 survey, 59% of dogs in the United States were overweight or obese, with 37% overweight and 22% obese. Just as telling, 36% of owners whose dogs were overweight described their dog as a normal weight.

Treats and chews are one of the easiest places for extra calories to hide, because they do not feel like food. A 20 lb dog that gets an average 6-inch stick every day on top of full meals is eating close to a fifth more than it needs, according to the table above.

• You should be able to feel your dog's ribs easily under a thin layer, without pressing hard.
• From above, there should be a visible waist behind the ribs.
• From the side, the belly should tuck up toward the back legs.
• If you are not sure, ask your vet for a body condition score at the next visit.

Small dogs, puppies and big dogs

Small dogs feel bully stick calories most. For a 10 lb dog, an average 6-inch stick is about 30% of the day's calories according to Tufts, which is three times the whole treat budget. That does not mean no bully sticks. It means short sessions on a longer stick, a holder if the dog chews fast, and meals trimmed on chew days.

Puppies have small stomachs and tight calorie budgets that also have to cover growth. Keep sessions short and talk to your vet about your puppy's target before making bully sticks a routine.

Large dogs have more room, but they also tend to get the biggest sticks. A 12-inch thick stick can be well over 200 calories, and a large dog that gets one most days still needs the meal adjusted. If you are comparing chews by calories, bully sticks are the only common chew with an independent measurement, which is worth knowing when a label gives no figure.

What about INVIROX bully sticks?

We want to be straight about this. We do not have a laboratory calorie figure for INVIROX bully sticks, so we are not going to print one. What we can share is the guaranteed analysis on every bag: crude protein 83% minimum, crude fat 5% minimum, crude fiber 1% maximum and moisture 12% maximum.

INVIROX bully sticks are a single ingredient, grass-fed Brazilian beef pizzle with nothing added. Until we have a lab figure, treat the study's ranges as a general guide for any bully stick, ours included, and let your dog's weight over the following weeks tell you whether the meal trim is right.
