Pale Gums in Dogs

By the Dog Health Handbook team · Updated · Fact-checked against current veterinary references (see sources)

Key takeaways

  • Healthy gums are moist and pink; color should return within about 2 seconds after pressing.
  • Pale or white gums mean anemia or poor blood flow, such as shock.
  • Pale gums with weakness, collapse or fast breathing are an emergency.
  • Common causes include internal bleeding, IMHA, rat poison, bloat, heart disease and kidney disease.
  • Rat poison bleeding starts 3 to 7 days later, so go to the vet even if your dog seems fine.

Healthy dog gums are moist and a light, salmon or bubblegum pink. Pale or white gums mean there is less red blood reaching the gums, either because the dog is anemic (short of red blood cells) or because blood flow is poor, as in shock.1,2,3 Common causes include internal bleeding, for example from a ruptured spleen tumor, immune-mediated anemia, rat poison, bloat, heart problems and kidney disease.4,2,5,6,7 If your dog has pale or white gums and is weak, collapsing or breathing hard, go to an emergency vet now. Pale gums in a dog that otherwise seems well still need a vet visit the same day.2,3,1

Go to an emergency vet now if your dog has:

  • White, gray or blue gums2,1
  • Pale gums with weakness, collapse or fast or labored breathing2,5
  • Pale gums with a swollen belly, or retching without bringing anything up (possible bloat)5,7
  • Possibly eaten rat or mouse poison, even if they seem fine, because bleeding usually starts 3 to 7 days later6
  • Yellow gums with red or brown urine8,9

Pale pink gums in a dog that is bright and eating, or new pinpoint red spots or bruises, need a vet visit the same day.3,10

What the Research Says

  • Gum color is one of the first things emergency vets check. In the Merck Veterinary Manual's triage guide, pale or white gums point to anemia or shock, and color should return within about 1 to 2 seconds after pressing.1
  • Rat poison bleeding is delayed. Clotting tests usually change 2 to 5 days after a dog eats anticoagulant poison, and bleeding typically starts 3 to 7 days after.6
  • Losing blood quickly is dangerous. Losing about a third of the body's blood quickly can cause shock, with pale gums, a fast heart rate and low blood pressure.4,9
  • Many splenic masses are cancer. Up to two-thirds of splenic masses are cancer, and a bleeding mass can cause sudden collapse with pale gums.5

How to Check Your Dog's Gums

  1. In good light, gently lift your dog's upper lip and look at the gum above a canine or back tooth.3,2
  2. Some dogs have naturally black or spotted gums, including Chow Chows, Shar-Peis and many Labradors and German Shepherds. Look for a pink patch instead.2,3
  3. Press a fingertip on a pink area until it turns white, then let go. Color should return within about 2 seconds. This is the capillary refill time.1,2,3
  4. Feel the gums. Dry or sticky gums suggest dehydration.3
  5. Take a photo in good light to show your vet. Stop if your dog won't let you look, rather than risk a bite.3

What Different Gum Colors Mean

Gum colorWhat it can meanHow urgent
Pink and moist, refills in about 2 secondsNormal1,2None
Pale pink or whiteAnemia, blood loss, shock or low blood pressure; sometimes pain or fear1,3Pale pink: same day. White, or pale with weakness, collapse or hard breathing: emergency
Blue, gray or purpleNot enough oxygen or poor circulation2,1Emergency
YellowJaundice from liver disease or red blood cell destruction1,2Same day
Bright or cherry redHeatstroke, some poisons such as carbon monoxide, or very high blood pressure2,3Emergency if heatstroke is possible
Muddy brownRare; poisoning from some human pain relievers, or severe shock3,1Emergency
Pinpoint red spots or bruisesLow platelets or a platelet problem11,10Same day

Causes of Pale or White Gums

Bleeding

  • Internal bleeding from a ruptured tumor of the spleen or liver, such as hemangiosarcoma, can cause sudden collapse, pale gums, fast breathing and a swollen belly.5,12,4 See spleen tumors in dogs.
  • Rat and mouse poison that stops blood from clotting can cause bleeding into the chest, belly, gut or skin days after it is eaten.6 See poisoning in dogs.
  • Injury or surgery, bleeding stomach or gut ulcers, and bleeding disorders.9,4
  • Parasites: heavy flea or hookworm infestations can cause severe anemia, especially in puppies.13,14

Red blood cells destroyed or not made

  • Immune-mediated hemolytic anemia (IMHA), where the immune system attacks red blood cells, is the most common cause of red cell destruction in dogs. The gums may be pale or yellow.9,8
  • Onions, garlic and zinc (for example, a swallowed coin) can destroy red blood cells.15,4
  • Tick-borne infections such as Babesia and Ehrlichia.16,9,17 See tick diseases in dogs.
  • Long-term illness such as kidney disease, hormone disorders or cancer can slowly lower red cell production.18 See kidney disease in dogs.

Shock and poor circulation

  • Bloat (gastric dilatation-volvulus): retching without vomiting, a swollen belly, drooling and pale gums. It is fatal without emergency surgery.7 See bloat in dogs.
  • Heart disease can cause pale or bluish gums along with coughing, fast breathing and tiring easily.2,3,19 See congestive heart failure in dogs.
  • Severe infection, trauma or dehydration can lead to shock.1,3

What Your Vet Will Check

TestWhat it shows
Gum color, refill time, heart rate, pulse and temperatureWhether your dog is in shock and how urgent things are1
Packed cell volume (PCV) and total proteinHow anemic your dog is; low protein points to blood loss4
Complete blood count with a smear and young red cell (reticulocyte) countWhether the bone marrow is responding, and clues such as parasites or damaged cells4,20
Platelet count and clotting testsBleeding causes such as low platelets or rat poison11,6
Chemistry panel and urine testKidney and liver disease, and bilirubin from red cell breakdown4
Ultrasound or X-raysBleeding into the belly or chest, a spleen mass, or a swallowed metal object9,5
Tick-borne disease testsBabesia, Ehrlichia and Anaplasma20,21

See blood tests for dogs for what each number means.

Frequently Asked Questions

Can a dog have pale gums and be OK?

Poor light or naturally dark gums can make gums look pale, and fear or pain can briefly blanch them. True pale gums are never normal, though, so have your dog checked the same day.

What does it mean if my dog has white gums and is breathing heavily?

This can mean severe anemia, internal bleeding or shock. Go to an emergency vet now.

What do I do if my dog's gums are pale?

Keep your dog calm and quiet and call your vet. If your dog is weak, collapsing or breathing hard, go straight to an emergency clinic.

Can worms cause pale gums in dogs?

Yes. Hookworms and heavy flea infestations can cause anemia and pale gums, especially in puppies.

Can stress cause pale gums in dogs?

Fear or pain can make gums look paler for a short time. If they stay pale, see your vet.
