Occasionally when I was in practice, I’d get a visit from concerned owners because they saw blood spots in their dog’s bedding, stools or on their anus. I would explain the reasons they might see blood around or from the anus and what to do. In this article, we’ll look at why dogs bleed from the anus, when you can try to help your dog at home, and when it’s time to head to the vet.
Most frequent conditions resulting in bleeding from a dog’s anus [with home remedies]
Noticing blood around your dog’s anus can be distressing, so understanding the top reasons for bleeding from the anus can prepare you to know the best way to help your furbaby.
1. Anal gland disease
One of the most common causes of anal bleeding is anal gland issues. If your dog’s glands don’t discharge properly, they can become impacted. The pressure and inflammation sometimes can cause an abscess or infection. Under these circumstances, the sac may ooze bloody pus.
Anal gland disease is fairly common in canines. The condition can affect any age or breed of dog. Impactions and abscesses are serious conditions. Without treatment, an infection may spread to the body, or an abscess can rupture and cause damage to the anus and rectum.
Signs of anal gland disease include:
- Scooting or dragging the butt across the floor to relieve pressure
- Excessive licking/biting at the tail head or around the anal area
- Clamping the tail down
- Discharge on bedding or other surfaces
- Sensitivity around the butt – some dogs may growl or snap if you touch the area
- Bleeding or pus from the anus
- Characteristic fishy odor
- Straining to defecate, possibly with vocalization
- Swelling around the anus that may be red and feel hot to the touch
If you notice signs of impacted or swollen anal glands, there may be some things you can try at home. While some people recommend you manually express your dog’s sacs, you should never attempt this without your vet’s direction and approval. Improperly expressing the anal sacs can cause tissue damage.
However, you may be able to comfort your pooch and encourage the natural draining of the anal sacs by:
- Applying warm compresses of water or salt water to the gland openings
- increasing dietary fiber to firm up the stools
- Exercising your dog to stimulate normal bowel movements and opening of the ducts
When your dog’s anal gland disease causes abscesses, infections, or anal bleeding, you should take him to the vet. Depending on the severity of your dog’s condition, the doctor may:
- Lance and drain swollen abscesses
- Drain and flush the anal glands
- Surgically remove the anal sacs
- Prescribe anti-inflammatories or steroids to reduce swelling
- Prescribe antibiotics for infections
2. Dietary issues
Dogs with food intolerance or who eat something their digestive system can’t process may develop an inflammation of the intestines known as colitis. Common symptoms of colitis are:
- Fresh blood in the stool
- Soft or watery stool
- Straining to poop
- Abdominal pain
- Increased frequency and urgency of bowel movements
If your dog suffers from colitis triggered by food, it’s usually manageable. You can try fasting your pup for 1-2 meals and then feeding him a bland diet like lean chicken and boiled rice to rest the gut. Additionally, supplement the food with probiotics to soothe the gut and help restore normal digestion.
Take your dog to the vet if his symptoms continue for more than 1-2 days. Ongoing bleeding can cause anemia, and repetitive vomiting can cause dehydration. The doctor can examine your pooch and initiate treatment, which may include:
- IV fluids
- Antibiotics to prevent secondary infection
- Changing your dog to a hypoallergenic diet
3. Intestinal parasites
While usually most common in puppies, intestinal parasites can infest any age dog. Our dogs investigate their surroundings with their mouths and may pick up eggs or larvae from the environment. Signs of parasite infestation include:
- Blood in the poop(stool may be formed, soft, or liquid)
- Rubbing or licking at the hind end
- Worms in the poop or around the anus
- Pot-bellied abdomen
- Vomiting(you may see worms in the vomit)
If you suspect that your dog has worms, you can try a few home remedies to remove the parasites (after discussing the situation with your veterinarian):
- Pumpkin seeds – ground pumpkin seeds contain the amino acid cucurbitacin, a natural anthelmintic, which can paralyze roundworms and tapeworms. As a result, the worms can’t attach to the intestines and are pooped out.
- Diatomaceous earth – Food-grade diatomaceous earth is generally harmless to your dog but contains microscopic fossils that can damage the worm’s exoskeleton and cause it to dry out or die.
- Chopped carrots – Coarsely-chopped carrots may help to dislodge intestinal parasites from the digestive tract so that your dog poops them out. They’re also a nutritious treat most dogs enjoy.
These measures aren’t always successful, and some remedies can be dangerous if you give too much or apply them wrongly. Talk to your veterinarian before attempting natural approaches, and seek medical treatment if:
- Your dog doesn’t improve in a 1-2 weeks
- Your dog has repeated vomiting and diarrhea
- Your dog becomes dehydrated
- Your dog stops eating
- Your dog becomes weak or lethargic
For severe infestations or cases that don’t respond to home remedies, bring a stool sample to your veterinarian. Leaving parasites untreated in your dog can lead to anemia from blood loss, blockages, or other conditions. The doctor can examine your dog’s feces and prescribe a deworming agent to eliminate the worms.
Your dog can have bloody stools or diarrhea with certain viral or bacterial infections like Salmonella or parvovirus. Signs of infection may include:
- Red blood on the surface of the poop
- Formed or soft/runny stools
- Straining to defecate
- Increased number of bowel movements
- Loss of appetite
- Abdominal discomfort
When infections are very mild, your dog may be able to overcome them. Provide supportive care to help your dog:
- Fast your dog for a day
- Offer a bland diet such as boiled rice and lean chicken
- Supplement the food with probiotics to restore digestive health
- Provide free choice drinking water
Seek veterinary treatment when symptoms won’t resolve in a few days, or if your dog has

- Uncontrolled vomiting and diarrhea
- Weakness or depression
- Pale gums
Your veterinarian will complete an examination and run diagnostic tests to determine the cause of the bleeding. Treatment may include:
- IV fluids
- Antiemetic drugs
- Antidiarrheal drugs
5. Hemorrhagic gastroenteritis
The cause of hemorrhagic gastroenteritis (HGE) has not been identified yet. When dogs develop HGE, it usually starts suddenly and may include symptoms like:
- Bloody diarrhea that often resembles raspberry jam
- Abdominal pain
- Loss of appetite
Dogs with HGE lose fluids and electrolytes rapidly, and they can die without supportive veterinary care. With a physical examination and diagnostic tests, the doctor will rule out other causes and make a presumptive diagnosis. Treatment usually includes;
- IV fluids that include potassium and electrolytes
- Antibiotics to counteract secondary infections
- 24-hour fast followed by a bland diet
- Pain medications
- Gastroprotective drugs like sucralfate
- Antiemetic drugs
- Probiotics to restore healthy gut flora
When is it OK to try and help my dog at home?
Many times, you can try helping your dog at home when your dog shows mild symptoms. For example, mild infections and dietary disturbances can often resolve with supportive care. Additionally, you may be able to provide first aid or home remedies for mild anal gland issues or intestinal parasites. We still recommend that you call your veterinarian to discuss your particular situation based on your dog’s overall health profile.
As long as your dog is acting normal, the bleeding is minimal/intermittent, and he’s still eating and drinking, you’re usually safe to monitor his condition and treat him at home. If you have any doubts, call your veterinarian and share your dog’s symptoms.
How to get started with helping your dog at home
If you notice bleeding from your dog’s anus:
Approach him carefully to get a closer look. If your pup has a recent injury, he may act aggressively out of fear or pain.
Check your dog
If possible, ask someone to assist you as you assess your dog

- Check his respiratory and heart rates
- Check his gums for a healthy pink color and press lightly to see how quickly the color returns
- Check his anus and try to determine the source of the bleeding – look for signs of
- Intestinal parasites
- Anal sac swelling or impaction
- Injuries or abrasions
- Blood coming from inside the intestinal tract
Initiate home care
If the bleeding is minimal or intermittent, apply appropriate remedies to comfort and support your dog. This may include
- Fasting your pup for 1-2 days
- Feeding a bland diet to rest an irritated gut
- Giving your dog probiotics
- Giving your dog plenty of fresh water to maintain hydration
- Increasing fiber in the diet to increase stool firmness
- Using remedies/treatment described above for anal glands or intestinal parasites
Most remedies are designed to support and comfort your dog but will not cure the disease. With mild conditions, your dog’s immune system may be able to overcome the problem. However, if your dog doesn’t improve in a few days to a week, or if other symptoms arise, contact your veterinarian. There may be an underlying condition that requires attention.
Frequently asked question:
Can I use an over-the-counter cream for my dog’s bleeding anus?
Mild over-the-counter creams with zinc or castor oil are generally safe for topical use on your dog’s bleeding anus. You may also be able to use plain Neosporin. However, none of these creams should be ingested. If you choose to apply a cream, watch your dog closely to ensure he does not lick the area. Creams are a temporary measure at best.
When should I seek veterinary care for my dog’s bleeding anus?
When your dog starts bleeding from the anus, it’s not always a veterinary emergency. By checking your furbaby’s vital signs and trying to determine the nature, amount, and source of the bleeding, you can determine whether it’s time to head to the vet or if you start with at-home treatment.
However, you should take your dog to the vet if:
- The bleeding doesn’t clear up in a few days
- There’s bloody diarrhea
- The stool is black and tarry
- Your dog is vomiting
- Your dog refuses to eat
- Your dog is lethargic, weak, or depressed
- The anal glands are swollen and oozing blood and pus
- Your dog has pale gums
