The clear jelly discharge from dog’s anus aids in lubricating the stool, making it easy to go through the anus.
Sometimes, finding a little anal gland fluid doesn’t mean anything serious.
However, if you see a lot of clear fluid coming out of the dog’s bum, it may indicate an anal sac disease.
The most typical reason for excessive mucus coming out of dogs include parasitic and viral infections, anal sac gland inflammation, stress, or spoiled foods.
Let’s find out why slime coming out of a dog’s bum happens and what to do if you see it.
Why Is There Clear Jelly Discharge From Dog’s Anus?

It’s normal when there is a little bit of clear liquid from the dog’s bum and no smell.
Dog’s anus leaking clear fluid helps moisten and lubricate the colon for the stool through with ease.
However, excessive mucus paired with vomiting, continuous diarrhea, and blood in the stool may reveal some digestive diseases or anal gland impaction.
The following issues may be the causes of excessive clear fluid coming out of dog’s bum.
Dietary Indiscretion
Your dog may have colitis if he digs the trash and eats spoiled foods. Allergic colitis often results in visible mucus in the stool.
Food intolerance or allergy to certain proteins are other causes for the clear liquid from dogs’ bums. If you suddenly change your dog’s food, he may suffer from stomach upset.
You should step-by-step change your dog’s diet. Start by adding a small amount of the new food to the old food.
Then, you can gradually increase the new food until the dog is entirely on the new diet. Your dog should adapt to a new diet within a week, and his stool should return to normal.
After that, the dog’s anus leaking clear fluid will go away. However, if it lasts, you must bring your dog to the vet.
Irritable Bowel Disease
Your dogs may also suffer from irritable bowel syndrome (IBS). The inflammatory cells continuously attack the gut.
Most IBD comes up with infiltration of lymphocytes and plasma cells. Dogs with IBD typically have a lot of mucus in stool and continuous diarrhea.
Anal Gland Infections
Whipworms and tapeworms are one of the most dangerous parasites.
Dogs suffering from the infection caused by these pesky parasites frequently experience diarrhea with mucus coming out of the dog.
Giardia and Cryptosporidium infections can also result in clear liquid from the dog’s bum. Giardiasis in dogs also causes foamy and runny diarrhea with a fishy smell.
Bacterial Infection
Dogs eating spoiled food or uncooked meat might suffer from food poisoning. Salmonella and E. coli are two of the most common bacteria.
They may develop inflammation in the dog’s intestinal tract, resulting in bloody mucus and chronic diarrhea. These symptoms may be accompanied by vomiting, lethargy, and weight loss.
Parvovirus
Parvovirus also causes anal sac disease. The common symptoms of parvovirus include lethargy, violent vomiting, bloody diarrhea, loss of appetite, and dehydration.
This virus infection is fast infectious. Puppies and dogs without vaccinations are at the highest risk of being infected.
Intoxication
If your dog eats chocolate, gum, or raisins, they may suffer from food poisoning. Vomiting and continuous diarrhea accompany shaky walking, exhaustion, fainting, and seizures.
Small Intestinal Bacterial Overgrowth (SIBO)
SIBO develops when the bacteria in the dog’s gut consume undigested food and overpopulate. It results in an imbalance of gut microbiota.
The common symptoms of SIBO are yellow mucus, soft or loose stools, clear liquid from the dog’s bum, and severe diarrhea.
If the unbalanced bacterial population is the cause, your dog can take fortiflora to reestablish equilibrium.
Stress
The dog’s mental and emotional health may significantly impact his intestinal function.
Dogs with stress colitis often have slime coming out of dogs bums and bloody poop sometimes.
Some reasons for stress in dogs may include the following:
- Transfer to a new house
- Boarding at a kennel
- The presence of a new family member
Addressing the stressors can stop excessive clear fluid from the dog’s bum within a few days. Call a veterinarian if this issue does not stop in 24 to 48 hours.
Symptoms of Mucus in the Stool in Dogs

A small amount of mucus in the stool often shows no health issue. You need to call the vet when seeing the following symptoms.
Abdominal Pain
If your dog has abdominal pain but still wants to drink and eat, the dog’s parent may try to give him a bland diet first.
The stomach upset usually goes away after a few days without treatment.
If the mucus in a dog’s stool comes with non-stop abdominal pain, you must bring your dog to the vet for examination as soon as possible.
Vomiting
Vomiting in dogs may occur for some reasons. Perhaps your dogs ate something strange or have consumed too much grass.
However, if the vomiting and loss of appetite last for a few days, you need to seek a veterinarian for dog treatment.
Diarrhea
An infection by a virus or bacterium is the main factor that causes diarrhea. Dogs with diarrhea require special care since they are at a high risk of dehydration.
If you see blood clots in the dog’s watery stool, contact the vet for an emergency.
Lethargy
Lethargy in dogs may be a symptom of parvovirus, kennel cough, distemper, and leptospirosis.
Thus, if lethargy comes with mucus from the dog’s anal glands, it may indicate a certain disease in the digestive tract.
Fever
A dog with a fever may have a body temperature over 103° F. When temperatures hit 106° F, complications might happen and put your dog to death.
Loss Of Appetite
Dogs’ appetite loss is normal if it suddenly happens and stops after a few days.
However, if it lasts day by day, it indicates serious diseases, such as systemic infections, kidney failure, or liver problems.
Color Change In The Stools
- Black and tarry
The stomach or upper intestine blood typically results in black and tarry stool. If you see this type of feces, collect it and contact your veterinarian for a fecal examination.
- Blood in the stool (red)
Fresh blood in the stool might be a sign of lower intestinal bleeding. Collect a stool and meet the veterinarian for help.
Parasites In The Stool
Whipworms are similar to small thread strands with one enlarged end. Roundworms can be several-inch long and look like spaghetti.
You can’t see tapeworms in a dog’s stool. You may discover their egg sacs that look like rice on a dog’s stool or behind.
Discharge Colored Mucus
It’s normal if the dog has pale yellow-brown or grayish discharge from his anus.
Once you see your dog leaking yellow fluid from his anus, it’s a symptom of the infected anal sac.
The signs below tell you when the discharge from a dog’s anus is abnormal or not.
1. White Discharge
Like the clear fluid coming out of a dog’s bum, the white discharge from a dog’s anus is a normal mucus of a healthy dog.
The anal glands produce this white slime to moisten and lubricate the dog’s stool, making it easy to enter the anus.
2. Dark Discharge
The dark leakage from the dog’s anus may be a symptom of the anal sac impaction.
The inflammation of the ducts will result in blocked anal sacs, which will discharge the pasty, brown substance.
3. Yellow Discharge
A yellow discharge from the dog’s anus occurs when the anal gland infection occurs.
When the condition worsens and causes a hot, painful swelling in the gland, it becomes an abscess disease.
4. Green Stuff Coming Out Of Dogs Bum
If you don’t treat the dog’s abscess, the anal gland may rupture. The anal gland ruptures may leak greenish-yellow or crimson pus.
5. Dog Bleeding From Anus Dark Red
The dark red fluid leaking from your dog’s anus may result from the blood inside the digestive tract. It’s an immediate concern that requires medical help.
How To Diagnose Why Slime Is Coming Out Of The Dog’s Bum?

The clear jelly discharge from the dog’s anus will stop shortly.
However, if the issue happens every day, you should meet the vet for a diagnosis to determine if there are other underlying diseases.
Step 1: Medical History Investigations
Your veterinarians will require a thorough medical history of the dog to make a diagnosis. They may ask you about your dog’s food, daily diet, and vomiting or diarrhea.
Step 2: Do Diagnostic Tests And Fecal Examination
The vet may ask your dog to do a rectal examination, anal examination, and additional testing to identify the underlying reason.
The veterinarian can check whether adult parasites are in the dog’s digestive tract.
The Giardia tests may help the vet see the parasite Giardia intestinalis. The cytology test can observe cancer cells and body fluids.
If there is no sign of these diseases, it’s necessary to investigate the stress and other chronic causes of the inflammation.
Leakage From Dogs Anus: Treatment And Recovery
After the accurate diagnosis, the vet can probably identify the underlying issue and provide you with a treatment and remedy to stop clear liquid from coming out of the dog’s bum.
The underlying issue will determine how you should treat it. Because there are various reasons, we have numerous treatments.
Diet Change
If stress and food allergy are the cause, the dog’s anus leaking clear fluid will stop on its own in a few days.
Sometimes, your veterinarian may recommend a hypoallergenic diet and probiotics suppleness.
Fasting and eating a bland diet with chicken and lamb dog food for allergies for a few days may help. In addition, probiotics help to regenerate good intestinal flora.
The vet may also ask you to feed your dog a diet with adequate fiber. Adequate dietary fiber may change stool consistency, stopping the leakage from the dog’s anus.
Drug Treatment
If there are intestinal parasites, the vet will recommend antifungal treatments to eliminate all parasites and resolve other anal sac diseases.
Following antibiotic or antifungal drugs, the infected dog may need probiotics to speed the recovery.
You must give your pet a full course of medication to avoid the anal gland issue recurring.
Surgery
The vet may recommend surgery for an intestinal obstruction or a polyp. If there is a tumor or other growth, it’s necessary to conduct a surgical removal.
The anal sacculectomy usually works. It may result in long-term relief for dogs suffering from anal gland impaction, infections, and abscesses.
How To Prevent Clear Liquid Coming Out Of Dogs Bum?
The intestinal parasites are the most common factor that causes clear fluid to come out of the dog’s bum. Thus, it’s crucial to keep your pet up-to-date with parasite prevention.
Routine parasite prevention helps to reduce the possibility of anal gland disease happening.
Moreover, probiotic supplements can support a healthy digestive tract and reduce inflammation and bacterial infections.
You should also pay attention to the dog’s diet. Special diets with high-quality food will prevent abdominal pain, stress colitis, and anal gland cancer.
Additionally, I recommend meeting the vet for a yearly fecal examination to look for intestinal parasites.
Veterinarians utilize microscopes to carefully examine what is actually inside the digestive system that we can’t see with our eyes.
