Horse Dropping Feed or Quidding: Dental Problem Signs in Horses

Quidding means a horse forms partially chewed feed into a ball and then drops it. In horses, this most often points to oral pain or poor tooth alignment rather than a behavior problem. Merck notes that classic signs of equine dental disease include slow eating, quidding, drooling, bad breath, weight loss, and sometimes uncrushed grain in the manure.

The most common causes are dental disorders such as sharp enamel points, hooks, ramps, uneven wear, periodontal disease, fractured teeth, loose or retained caps in younger horses, and tooth decay or root infection. These problems can make chewing rough forage painful, so a horse may avoid chewing fully, tilt the head, or stop and restart while eating.

Some horses also drop feed because of mouth ulcers, bit-related soreness, foreign material in the mouth, or less commonly problems deeper in the throat or esophagus. If painful chewing leads your horse to swallow feed too quickly, that can increase the risk of choke, indigestion, or colic.

Age matters too. The AAEP advises that mature horses should have a thorough dental exam at least yearly, while horses 2 to 5 years old often need exams twice yearly because retained caps and eruption-related problems are more common during that stage.

See your vet soon if your horse is repeatedly dropping hay or grain, eating more slowly than usual, losing weight, drooling, resisting the bit, or showing bad breath. Those signs strongly suggest a painful mouth or dental problem that usually cannot be sorted out by looking from the outside.

See your vet immediately if quidding happens along with feed material coming from the nose, repeated gagging, obvious distress while swallowing, colic signs, one-sided nasal discharge, facial swelling, blood-tinged saliva, or a sudden refusal to eat. Those findings can go beyond routine dental wear and may signal choke, a tooth-root infection, sinus involvement, or another urgent problem.

It is reasonable to monitor briefly only if you saw one isolated episode, your horse is otherwise bright, eating, drinking, and passing manure normally, and there are no other warning signs. Even then, if the problem happens again, schedule an exam. Waiting too long can allow weight loss, mouth ulcers, and more advanced dental disease to build.

Do not put your hands deep into your horse's mouth or try to rasp teeth at home. Horses need a safe, thorough oral exam, and your vet may recommend sedation and a full-mouth speculum to evaluate the cheek teeth properly.

Your vet will start with a history and physical exam, asking when the quidding started, whether it affects hay, grain, or both, and whether there is weight loss, bad breath, nasal discharge, choke history, or performance changes. They may also ask about your horse's age, last dental visit, and whether unchewed grain is showing up in the manure.

A proper dental workup usually includes sedation if needed, placement of a full-mouth speculum, and a detailed oral exam. According to AAEP guidance, a typical equine dental exam may involve sedation, opening the mouth with a speculum, inspecting the teeth, and floating sharp points or hooks when indicated.

Depending on what your vet finds, they may recommend routine floating, removal of retained caps or wolf teeth, treatment for periodontal pockets, pain control, or antibiotics if infection is present. If there is facial swelling, one-sided nasal discharge, or concern for a fractured or infected tooth, your vet may suggest dental radiographs, oral endoscopy, or referral for advanced dental procedures.

Your vet will also look for complications caused by poor chewing, including weight loss, choke risk, and secondary digestive upset. The treatment plan should match your horse's age, comfort, workload, and the severity of the dental findings.

Home care should focus on comfort, safe eating, and close observation while you arrange veterinary care. Offer easy-to-chew forage or soaked complete feeds only if your horse is still swallowing normally and your vet agrees. Pick up dropped feed wads so you can monitor how often quidding is happening, and keep notes on appetite, manure output, and body condition.

Make sure fresh water is always available. Some horses with mouth pain are reluctant to chew coarse hay or hard grain, so forcing normal feed can make the problem worse. If your horse has trouble swallowing, feed coming from the nose, gagging, or distress while eating, stop offering feed and call your vet immediately.

Do not try to examine the back teeth yourself, pull loose teeth, or use over-the-counter sedatives or pain medications unless your vet specifically directs you. Equine mouths are deep, strong, and easy to injure accidentally. A proper dental exam is safer and far more informative.

After treatment, follow your vet's feeding and recheck instructions closely. Many horses feel better quickly after dental correction, but those with ulcers, periodontal disease, or extractions may need a softer diet for a period and a scheduled follow-up to confirm they are chewing normally again.
