Dog broken nail bleeding, hanging, exposed quick, or possibly infected? Upload a photo — AI assesses severity (minor / moderate / severe / emergency), tells you whether to treat at home, and gives step-by-step next steps. ⚠️ Active heavy bleeding that won't stop, severe pain, or nail torn at base = go to vet immediately; AI analysis can wait.

Good photos

Avoid

Too much blood

Too far away

Take a clear photo of the broken nail and surrounding toe. Include both the damaged nail AND a healthy adjacent nail for comparison if possible. If bleeding, take the photo after initial bleeding is controlled.

Our AI examines: break location (tip vs mid-nail vs base), whether the quick (pink sensitive tissue) is exposed, whether the nail is attached/hanging/completely off, presence of bleeding, and early infection signs (swelling, redness, discharge).

Receive a severity assessment (minor / moderate / serious / emergency), step-by-step home treatment if appropriate, OR clear "go to vet" guidance with urgency level. Plus infection-monitoring checklist if nail already broken for 2+ days.
Broken dog nails range from minor tip cracks (leave it alone) to serious base breaks (vet-visit required). Our AI identifies the type of break, assesses severity, and tells you whether home treatment is safe or vet care is needed. Below are the 6 main patterns. Also try our dog paw checker or dog wound checker or dog skin checker.
The mildest and most common nail injury. Pattern: visible crack running along the length of the nail, may be lengthwise ("split vertically") or short horizontal crack at the tip; nail still firmly attached; no exposed quick; no or minimal bleeding; dog walking normally or mildly favoring. Causes: running on hard surfaces, catching nail on carpet or fabric, dry/brittle nails (more common in senior dogs), nail overgrown and putting pressure on itself. TREATMENT AT HOME: if crack is at the tip and doesn't reach the quick, trim the damaged portion with dog nail clippers to prevent further splitting; file any rough edges; monitor for 2-4 weeks as nail grows out. Consider adding omega-3 fatty acids to diet for stronger nails going forward. NOT USUALLY URGENT: most small cracks heal without intervention. VET VISIT if: crack extends to the quick, becomes painful, shows signs of infection, or is on the dew claw (which may catch and worsen).


One of the MOST COMMON emergency scenarios. Pattern: nail is damaged mid-length, partially broken off but still attached by remaining tissue, fur, or a thin strand of nail; may be hanging at an angle; often bleeding; dog is visibly uncomfortable, limping, holding paw up. The loose portion CATCHES on things, dragging and pulling the remaining connection — this causes continued pain and prevents healing. IMPORTANT: DO NOT try to rip off a partially attached nail at home unless it comes off with near-zero resistance. The proper treatment is removal of the loose portion under sedation or local anesthesia, which allows the nail bed to heal cleanly. If the nail is hanging by just a thread and your dog is cooperative, using sharp dog nail clippers to cleanly snip the thread is sometimes acceptable. But if attached by more than a thread, has significant bleeding, or your dog is painful: vet visit. Vet will sedate, cleanly remove the damaged portion, clean and cauterize the nail bed, bandage, and send home with pain meds and usually preventive antibiotics. Healing timeline: 2-3 weeks for comfort, 3-4 months for full nail regrowth.
The QUICK is the pink blood vessel and nerve inside the nail — highly sensitive. When a nail breaks above the quick and the damaged portion comes off, the quick becomes exposed. Pattern: obvious pink/reddish tissue visible at the nail, often bleeding initially (sometimes heavily), very painful — dog may hold paw up continuously, cry when touched, avoid weight-bearing; sometimes still covered with the last bit of nail that is hanging. Causes: severe nail split that continues into the quick, traumatic break (caught on something, stepped on), over-trimming nails (cutting into the quick), or pre-existing thin nail becoming fully damaged. IMMEDIATE STEPS: (1) Stop bleeding with styptic powder + firm pressure for 5-10 minutes. (2) Once bleeding stops, gently clean with diluted chlorhexidine or warm soapy water. (3) Cover with gauze + light vet wrap (not tight). (4) Call vet — exposed quick warrants within 24-hour vet evaluation. Vet may: prescribe pain medication, prescribe preventive antibiotics, clean and debride, possibly trim remaining damaged nail under sedation. The exposed quick gradually dries into a protective "scab" over 3-5 days, then slowly recedes back to safer position over 2-3 weeks. AI confidence for this pattern: HIGH — exposed pink tissue is visually distinctive.


A break at the base (where the nail emerges from the paw) is the MOST SERIOUS type of nail injury. Pattern: nail is broken very close to the toe / paw pad, often the whole nail is cracked off or hanging by the base; significant bleeding; toe often swollen; dog will not put weight on the paw; severe pain. The nail-bed tissue is directly exposed, creating very high infection risk. The nail matrix (the tissue that grows new nail) may also be damaged, potentially affecting future nail growth. VET VISIT REQUIRED — within 24 hours, sooner if possible. Do NOT attempt home treatment beyond initial bleeding control. What the vet will do: sedation or heavy pain control; remove any remaining damaged nail; clean the exposed nail bed; cauterize or stitch if needed; prescribe oral antibiotics for 10-14 days (high infection risk); prescribe pain medication; apply bandage; e-collar for 2-3 weeks to prevent licking; follow-up visits to monitor healing. Cost: $200-500 typical, more if complications. Recovery: 3-4 weeks for initial healing, 3-4 months for nail regrowth (may grow back abnormal or not at all if matrix damaged). Dew claw injuries particularly common in this category since dew claws don't wear naturally.
Nail infections typically develop 2-7 days after a broken nail that wasn't properly treated, but can also develop from licking, foreign material under the nail, or systemic disease. Pattern: the TOE around the nail is SWOLLEN and RED; skin around nail bed looks angry and inflamed; there may be visible DISCHARGE or PUS (yellow, green, or cloudy); often BAD SMELL from the paw; dog licking excessively; limping worsening over days; in severe cases, fever and lethargy. Progression: starts as mild redness and swelling → develops into visible discharge → can progress to abscess → worst case, bone infection (osteomyelitis). VET VISIT REQUIRED — nail bed infections don't self-resolve; they spread. Treatment: oral antibiotics (cephalexin, clindamycin, or amoxicillin-clavulanate typical) for 10-21 days; sometimes culture to target treatment; pain medication; warm compresses; daily gentle cleaning; e-collar. Supportive home care during antibiotic treatment: cleaning with diluted chlorhexidine 1-2x daily, keeping paw dry, monitoring for improvement. If not improving within 3-5 days of antibiotics, vet may need to culture + change antibiotics, or rule out deeper infection. AI confidence for infection: HIGH when classic signs (swelling + discharge + redness) are visible. Multiple infected nails = consider underlying disease (diabetes, immune suppression).


Overgrown nails can break more easily, curl into the paw pad, or cause repeated nail injuries. Pattern: nails visibly long, curving downward or sideways; nails click loudly on hard floors; dog may spread toes abnormally to avoid nail contact; in severe cases, nail curves into pad causing secondary injury. DEW CLAWS (the "thumb" nail on the inner paw, sometimes on back legs too) are especially prone to problems because they don't contact the ground and don't wear naturally — they need manual trimming. Complications of overgrowth: nail catching and tearing, splaying of toe joints, paw pad punctures from ingrown nails, repeated quick damage from the owner trying to trim too short after overgrowth, pain when walking. Home management: regular nail trimming every 2-4 weeks with proper dog nail clippers or grinder; start slow if dog is fearful; take tiny amounts off at a time to avoid the quick; use flashlight from behind to see the quick on light-colored nails. If nails are severely overgrown, a VET VISIT for trimming under sedation may be needed — at-home trimming of very long nails often hits the quick. Prevention: regular walks on abrasive surfaces helps naturally wear nails; twice-monthly trims; positive reinforcement during nail care starting in puppyhood; check and trim DEW CLAWS every month. AI confidence for overgrown nails: HIGH when length is clearly excessive.
