What is Bleeding from the Mouth?

It can be very upsetting to find your dog bleeding from the mouth.  A small amount of blood from a nick should not cause you to be concerned.  However, if your dog is continuously bleeding from the mouth, he must be seen by a veterinarian as soon as possible. A foreign object could cause breathing difficulties and a condition such as an abscess could quickly become painful. 

Bleeding from the mouth may be caused by:

  • Laceration on the dog’s tongue or mouth
  • Oral trauma
  • Canine ulcerative paradental stomatitis (CUPS)
  • Abscess or fractured tooth
  • Gingivitis
  • Foreign object lodged in gums or throat
  • Blood clotting disease such as Von Willebrand’s Disease

It is important to find the cause of the bleeding.  Excessive bleeding is a serious condition which can cause your dog to go into shock. A bleeding dog with a clotting disorder may need to have an emergency blood transfusion.

Why Bleeding from the Mouth Occurs in Dogs

Laceration on the Dog’s Tongue or Mouth

Your dog may have cut his mouth or tongue by chewing on toys, sticks or even rocks.  A laceration can be caused by another animal bite (dog, cat, raccoon, rat or possum).  If your dog got into the garbage, he may have cut himself on a can or other sharp object.

Oral Trauma

Oral bleeding may be caused by a fall, impact with a car or by being physically hit on the mouth. Additionally, tongue trauma can occur during freezing temperatures; a dog licks metal and must then rip his tongue free (tongue gets stuck). 

Canine Ulcerative Paradental Stomatitis (CUPS)

 

Canine ulcerative paradental stomatitis is a disorder that causes painful ulcers on the lining of the dog’s mouth. The ulcers are triggered by plaque on your dog’s teeth.  The ulcers can open and bleed.  Breeds that are more predisposed to CUPS are the German Shepherd, Dachshund, Labrador Retriever and the Maltese.

Abscess or Fractured Tooth

An abscess or a fractured tooth may be causing your dog to bleed from the mouth. The abscess may cause additional symptoms such as facial swelling, fever, pain and loss of appetite.

Gingivitis

 

Gingivitis is the inflammation of the gums due to bacteria and plaque. Gingivitis is a very common condition in dogs.  The infected gums can become very painful, swollen and can also start to bleed.

Foreign Object

Dogs can get a piece of toy or stick stuck in between their teeth.  Grass seeds, fishing hooks and porcupine quills can also pierce the tongue, face, under the tongue or the gums. Foreign objects lodged in your dog’s mouth can cause great discomfort and bleeding.

Blood Clotting Disease

 

Von Willebrand’s disease is the most common inherited, blood clotting disorder in people and in dogs. It is caused by the deficiency of a clotting protein. There are three different types of Von Willebrand’s disease. They are classified by whether the clotting protein is reduced, moderate or completely absent. Without the clotting protein, the platelets are unable to bind together to stop bleeding. Without proper medical treatment, the patient can bleed to death.

What to do if your Dog is Bleeding from the Mouth

If your dog has prolonged or repeated bleeding from the mouth, he should be examined by a veterinarian. 

If your dog is heavily bleeding, the veterinarian team will first need to stabilize him. They may administer an IV to help keep your dog hydrated.  If the patient has lost a lot of blood, he may need a blood transfusion. 

After the patient is stable, the veterinarian may recommend a complete blood count (CBC) and x-rays.  If the CBC determined a low platelet count, the veterinarian may recommend a buccal mucosal bleeding time test and a specific blood test for Von Willebrand’s disease, which measures the levels of the clotting protein.

Dogs with dental or gum conditions may be referred to a veterinarian dentist.  Deep and large lacerations may need sutures.  The mouth will need to be cleaned several times a day with a disinfectant.  Your pet will not be able to eat hard kibble. The doctor may prescribe antibiotics to help prevent a bacterial infection.

If the veterinarian finds a foreign object in the dog’s mouth he will remove it.  Your dog will need to be sedated during the procedure.

Unfortunately, there is no cure for Von Willebrand’s disease in dogs but the disease can be managed and controlled.  The veterinarian may also recommend soft, wet food instead of dry kibble, which can cause gum bleeding. Hard chew toys and rough housing should be avoided.

Dogs with clotting disorders should not be given nonsteroidal anti-inflammatory drugs (NSAIDs), estrogens, heparin or sulfonamide antibiotics. 

Additionally, if your dog ever requires surgery, let the surgeon know that your companion has a clotting disorder.  The surgical team is then prepared and will have blood transfusions available.  It is also a good idea to know your dog’s blood type, in case of a bleeding emergency.

Prevention of Bleeding from the Mouth

Regular visits to a veterinary dentist may help prevent a tooth abscess, plaque and gingivitis.  It is a good idea to keep an eye on your dog when he is playing outside. Unsupervised dogs can chew on things they should not be chewing on (sticks, rocks grass seeds). Additionally, they can be attacked by wild animals or exposed to physical abuse. 

Von Willebrand’s disease is an inherited genetic condition.  The only way to prevent the disease is to not breed carriers of the disease.

Cost of Bleeding from the Mouth

The cost of treatment will depend on the veterinarian’s diagnosis.  The treatment of canine ulcerative paradental stomatitis may range from $500 to $4500.  The cost of treating gum disease can be $800.

Bleeding

My 12 year old male Beagle/Pomeranian mix has been bleeding quite a bit from his mouth. He is very sensitive when it comes to injuries so he won’t let me examine his mouth so I can’t tell exactly where the blood is coming from except that it’s definitely from somewhere inside his mouth. There is quite a bit of blood and this is the third time this has happened. The last 2 times happened when the vet was closed so I planned to take him in the morning but by morning he stopped bleeding so I thought he was ok. Now he’s bleeding again and it’s even more blood this time so I’m concerned. Once again it happened while his vet is closed. What could be wrong and What should I do? Thank you, any advice would be appreciated.

Bleeding From Mouth

Okay so this morning I came home from work to find that my 13 year old rottweiler mix had been bleeding from what looks like a loose tooth. She has been drinking water all day she has been eating normal and does not seem to be having any discomfort but tonight the bleeding came back a little. I am just concerned. Is this a need to go to the vet or is this normal at her age.

Tooth loss at this age isn’t unusual, but if the mouth is bleeding and there is a loose tooth you should visit your Veterinarian to have a look to see if it is normal tooth loss or if there is another underlying cause. They may also remove the tooth or help control the bleeding. Regards Dr Callum Turner DVM

My puppy was bit by another dog in the mouth and nose area. She has slight bleeding in her mouth where she was bit and her nose has a slight swelling where she was bit. Is this something that needs to be seen by a vet?

If the swelling over her nose gets worse, starts to become more swollen or has a discharge, or if Halo won't eat, then yes, you should see a veterinarian. If she seems not bothered by the area, and it seems to be healing well, you may not need to have her seen. Bite wounds can be dirty and can get infected, so keep a close eye on the area for the next few days.

Hi G.G is a 5 yr old chihuahuah. She has been bleeding from the gums for a week now. I took her to the vet, he said he thought she needed her teeth cleaned. They did a Thp with a standard CBC. I assumed we where going to go ahead and schedule her to have her teeth taken care of. Instead they sent us home and called the next day with test results. Saying her platelets where slightly low, also that she now needs to come in for a Full CBC and an ultra sound for her heart for heart worms as well as 2 other test I feel like im being given the run around, are all these extra test necessary??? Shes very healthly, still eating/drinking plays with her mom and dad as usual she just has slight bleeding with the blood trying clot but unable due to her saliva, im assuming.

Without more details, I have a very hard time commenting on what tests G.G. may need, but I am sure that there is a reason that they are recommending the tests. What you can do is ask them for further clarification so that you understand why they are suggesting these things for her. If it still doesn't seem to make sense to you, it might be worth getting a second opinion to see what another veterinarian thinks about her health status.

Why would my Australian bulldog be bleeding from his mouth quite a bit every time he goes on a walk. Even if its not the far at all. Like maybe 300m. He doesn't really have any other symptoms that i notice.

I'm not sure why Ocky is bleeding from his mouth when he walks, but that is not normal for a dog to have that problem. He may have a problem with his teeth, his mouth, or his lungs, and it would be a good idea to have him examined by a veterinarian to see what is going on that is causing that problem so that you can treat it for him.

Lethargy, Bleeding From Teeth/Gums

I have a 10 month old Shih-poo that started acted lethargic two days ago and then began bleeding from her gums yesterday. I took her to the vet yesterday and she was positive for Anaplasmosis (tick borne illness)and they started her on Doxycline. She went to play with her ball this morning and was bleeding again just from picking up her ball. She is definitely quieter than her usual spunky self. Can Anaplamosis be the cause of all her symptoms, or should we look for other causes of the mouth bleeding?

Bleeding From Mouth

Starting today, 6/24, my dog has been bleeding from her mouth every time she licks something or laps at something. She has bled from licking EVERYTHING. We tried giving her ice, ice water, and many other things to try and make her stop. She doesn’t seem to be in pain at all from it, but it makes me feel really sad to see her bleeding

Now 11 yr old boxer cut lingual frenulum 3 years ago on a nylabone. Required her to be sedated and stitched, soft food ordered for 10 days with antibiotics. At 11 she has recently began struggling with her dry dog food. I began softening her food about 2 weeks ago and she has returned to her normal eating pace. Tonight as she finished her dinner I discovered her frenulum bleeding. She has not actively chewed on any of her toys today. Is there a possibility that the soft food has strained her tongue where she previously had to have it stiched? The bleeding seems to be minimal as she has stopped licking in the manner that she was upon completing her dinner tonight. 3 years ago I did not discover the cut until the following morning. The cut caused her to slowly ingest blood which in turn irritated the lining of her stomach resulting in her committing a large amount of blood.

my chihuahua is around 11 years old and has lost a couple of his teeth recently. he just started bleeding from his mouth. it’s not much but it mainly happens at night or in the middle of the night. so far it’s only happened 5 times. it appears bright red and about the size of a dime or smaller. he hasn’t drank much water in the past 2 days nor has he eaten his dog food. i’ve given him white rice thinking he was throwing up blood until i realized its coming from his mouth somewhere. he’s also been acting completely normal even playing and running around. any advice would greatly help!
