Why Are My Dog's Gums Bleeding?

Discovering blood on your dog's toys, in their water bowl, or while brushing their teeth can be alarming. Bleeding gums in dogs are a significant warning sign that shouldn't be ignored, as they often indicate underlying dental or health issues.

Nerovet AI Dentistry helps pet owners identify gum problems early, before they become serious and costly to treat.

Common Causes of Bleeding Gums in Dogs

1. Gingivitis (Gum Inflammation)

The most common cause of bleeding gums. Gingivitis occurs when plaque buildup irritates the gums, causing:

  • Red, swollen gums
  • Bleeding when eating or during brushing
  • Bad breath
  • Sensitivity around the mouth

Good news: Gingivitis is reversible with proper dental care.

2. Periodontal Disease

When gingivitis progresses untreated, it becomes periodontal disease:

  • Gums pull away from teeth
  • Bone loss around teeth
  • Pus between teeth and gums
  • Loose or falling teeth
  • Severe bleeding

Warning: Periodontal disease is NOT reversible, but progression can be stopped.

3. Injury or Trauma

Physical causes of bleeding include:

  • Chewing hard objects (bones, antlers, rocks)
  • Broken or cracked teeth
  • Foreign objects stuck in gums
  • Burns from electrical cords
  • Fights with other animals

4. Oral Tumors or Growths

Abnormal growths in the mouth can:

  • Bleed easily when touched
  • Cause persistent bleeding
  • Create ulcers on gums
  • Appear as lumps or discolored areas

Important: Any unexplained growth should be examined by a vet immediately.

5. Blood Clotting Disorders

Less common but serious causes:

  • Von Willebrand's disease
  • Hemophilia
  • Rat poison ingestion
  • Immune-mediated thrombocytopenia

Signs include bleeding that won't stop and bruising elsewhere on the body.

6. Systemic Diseases

Underlying health conditions can affect gums:

  • Kidney disease
  • Liver disease
  • Diabetes
  • Autoimmune conditions

How to Check Your Dog's Gums

Perform a simple gum health check:

Color Check

ColorMeaning
PinkHealthy
Bright redInflammation
Pale/WhiteAnemia or shock
Blue/PurpleOxygen deprivation
YellowLiver problems

Capillary Refill Test

  1. Press gum with finger
  2. Release and count seconds for pink color to return
  3. Normal: 1-2 seconds
  4. Slow refill may indicate circulation problems

What to Look For

  • Swelling along gumline
  • Red line where gum meets teeth
  • Bleeding spots
  • Receding gums
  • Pus or discharge

First Aid for Bleeding Gums

If you notice bleeding:

  1. Stay calm - Don't panic your dog
  2. Gently examine - Look for obvious causes
  3. Apply pressure - Use clean gauze for active bleeding
  4. Remove foreign objects - Only if easily accessible
  5. Rinse gently - With clean water if debris present
  6. Monitor - Watch for continued bleeding

Seek immediate vet care if:

  • Bleeding doesn't stop within 10 minutes
  • Large amount of blood
  • Dog is lethargic or weak
  • Visible broken teeth or jaw injury
  • Suspected poisoning

Treatment Options

Home Care (Mild Cases)

  • Soft food diet temporarily
  • Gentle brushing with soft brush
  • Antiseptic dental rinse (vet-approved)
  • Dental water additives

Veterinary Treatment

  • Professional dental cleaning
  • Antibiotics for infection
  • Tooth extraction if necessary
  • Treatment of underlying disease
  • Biopsy of suspicious growths

Prevention Strategies

Keep your dog's gums healthy:

Daily Care

  • Brush teeth daily or every other day
  • Use enzymatic dog toothpaste
  • Provide appropriate dental chews
  • Avoid hard chew toys

Regular Monitoring

  • Check gums weekly
  • Use Nerovet AI for monthly scans
  • Note any changes in eating habits
  • Watch for pawing at mouth

Professional Care

  • Annual dental exams
  • Professional cleanings as recommended
  • Address problems early

How Nerovet AI Detects Gum Problems

Our AI system analyzes photos to identify:

  • Early inflammation - Before visible bleeding
  • Gum recession - Pulling away from teeth
  • Color changes - Signs of disease
  • Swelling patterns - Localized vs. widespread
  • Progression tracking - Changes over time

Early detection can prevent bleeding gums from becoming serious dental disease.

When Bleeding Gums Are an Emergency

Seek immediate veterinary care for:

  • Uncontrolled bleeding
  • Trauma to the face or jaw
  • Difficulty breathing
  • Extreme lethargy
  • Suspected poison ingestion
  • Bleeding with other symptoms (bruising, bloody urine)
