Weight is hard to judge by eye, especially under a winter coat or when you see your horse every day. Body condition scoring gives you a simple, hands-on way to check whether your horse is too thin, just right or carrying extra weight. Here’s how to use the Henneke scale.
Quick Answer: The Henneke body condition scoring (BCS) system rates horses from 1 (extremely thin) to 9 (extremely fat) by feeling fat cover in six areas. Most healthy horses should score about 4 to 6. Horses with metabolic issues or a history of laminitis should usually stay around 4 to 5.
Why Body Condition Matters
- Too thin: poor energy, weak immune system, trouble staying warm
- Too heavy: higher risk of laminitis, insulin problems, joint strain and heat stress
The Henneke system was developed by researchers at Texas A&M University and is widely used by vets, rescues and horse owners.
The Six Areas to Check
- Neck: fat along the crest and sides
- Withers: fat on either side of the withers
- Behind the shoulder: fat just behind the shoulder blade
- Ribs: how easily you can feel and see them
- Loin: fat along the back, especially a crease or ridge
- Tailhead: fat around the base of the tail
The Henneke Scale
| Score | Description | Key features |
|---|---|---|
| 1 | Poor | Extremely emaciated; spine, ribs, hips and tailhead very prominent |
| 2 | Very thin | Bones easily visible; slight fat over spine |
| 3 | Thin | Ribs easily visible; slight fat cover over ribs |
| 4 | Moderately thin | Faint outline of ribs visible; slight ridge along the back |
| 5 | Moderate | Ribs easily felt but not seen; back level |
| 6 | Moderately fleshy | Fat over ribs feels spongy; slight crease down the back |
| 7 | Fleshy | Individual ribs can be felt; fat filling between ribs; crease down back |
| 8 | Fat | Ribs hard to feel; thick neck; fat along withers and tailhead |
| 9 | Extremely fat | Obvious crease down back; patchy fat; bulging fat over ribs |
How to Score Your Horse
- Stand your horse squarely on level ground.
- Look at your horse from the side, front and behind.
- Run your hands firmly over each of the six areas.
- Score each area from 1 to 9.
- Average the scores for an overall BCS.
- Record the date and score.
Repeat every month, and more often if you’re changing the diet.
Ideal Scores
| Horse | Target BCS |
|---|---|
| Most adult horses | 4–6 |
| Easy keepers, metabolic or laminitis-prone horses | About 4–5 |
| Broodmares | About 5–6 |
| Performance horses | About 4–6 depending on discipline |
Other Tools: Weight Tape and Cresty Neck Score
- Weight tape: estimates body weight. Track changes over time.
- Cresty neck score (0–5): rates fat along the neck crest. A high score can signal insulin dysregulation and laminitis risk. See laminitis in horses.
If Your Horse Is Too Thin
- Rule out medical causes with your vet, including teeth, parasites and disease. See equine dental care and deworming horses.
- Increase forage first.
- Add calories with alfalfa, beet pulp or a high-fat feed as advised.
- Make changes gradually.
If Your Horse Is Overweight
- Feed hay at about 1.5–2% of body weight, adjusted with your vet.
- Use slow feeders and low-sugar hay.
- Limit lush pasture with a grazing muzzle or dry lot.
- Remove or reduce grain and treats.
- Increase exercise if your horse is sound.

When to Call Your Vet
Call your vet if your horse:
- Scores below 4 or above 7
- Loses or gains weight quickly
- Has a cresty neck, fat pads or signs of laminitis
- Is losing muscle along the topline, which can signal PPID
Frequently Asked Questions
Can I score my horse with a winter coat?
Yes, but you must feel through the coat. Visual scoring alone is misleading in winter.
How fast should an overweight horse lose weight?
Gradually, about 0.5–1% of body weight per week, under your vet’s guidance.
Does body condition score replace weighing?
No. Use both. Weight tracks changes, and BCS shows fat cover.
Is a score of 6 too fat?
A 6 is acceptable for many horses, but not ideal for those at risk of laminitis.
Do some breeds naturally score higher?
Breed builds differ. Draft breeds, Quarter Horses and many ponies carry more muscle and fat, while Thoroughbreds and Arabians tend to look leaner. The scale still applies, but compare against your horse’s healthy baseline.
Can I learn BCS from photos?
Photos help track changes over time, but you need hands-on scoring for accuracy, especially in winter.
What score should a horse in heavy work have?
Many performance horses do well around 5. Very lean horses may lack energy reserves.
