Rectal prolapse in dogs and cats occurs when the animal’s rectum (the last part of the digestive tract, where feces sits before it’s launched onto an unsuspecting world) pops out of the anus.
You may see a pink or red ring, or a longer tube of moist tissue, protruding from the anus. Rectal prolapse in dogs and cats needs prompt veterinary assessment, even when the tissue disappears again after a bowel movement.
Call your veterinarian immediately if tissue is sticking out. A full prolapse is an emergency: exposed tissue can dry out, swell and lose its blood supply. Prompt treatment gives the veterinarian more options for protecting and replacing it.

Mucosal Prolapse vs. Full Rectal Prolapse in Dogs and Cats
The rectum normally stays inside the body. In an incomplete or mucosal prolapse, its inner lining slips outward. In a complete prolapse, the full thickness of the rectal wall protrudes. The difference affects treatment, but neither appearance is something to diagnose or push back yourself.
Use your existing secure carrier for a cat or small dog, with room to lie comfortably and without pressure on the affected area. For a larger dog, ask the clinic about safe handling and unloading. A frightened, painful pet may bite even when normally gentle. A replacement carrier is useful for future trips, but buying equipment must never delay this visit.

| What you notice | What it may represent | What to do |
|---|---|---|
| A small pink rosette or ring during defecation that retreats afterward | An incomplete prolapse; the underlying cause of straining still needs attention | Call the vet promptly and describe what happened. A photograph, if safe to take, may help when the tissue is no longer visible. |
| A red or pink tube that stays outside the anus | A complete prolapse or another serious protruding-tissue problem | Arrange emergency veterinary examination and safe transport. Do not attempt to replace it. |
| Dark, dry, badly swollen or bleeding tissue | Possible damage to exposed tissue; appearance alone cannot establish whether it is viable | Go to an emergency clinic. Do not wait for a color change before seeking care. |

The first signs may be straining and a visible change at the anus when pooping. A puppy, kitten or adult pet can be affected. People sometimes describe a “prolapsed anus” or “prolapsed colon,” but the veterinarian needs to establish exactly which tissue is protruding. A canine prolapse and a feline prolapse both warrant prompt assessment.

Mucosal Prolapse Can Be Brief, but Still Needs Attention
You may notice a pink rosette of tissue around the anus just after your dog or cat has toileted. Tell the clinic whether it appeared only while straining, how long it remained visible and whether this has happened before. A short-lived episode does not show that the cause has resolved.
Set up a quiet resting area on clean, washable bedding. A familiar towel or blanket you already own may be sufficient; a washable waterproof blanket can protect the resting surface during recovery. It is bedding, not a dressing for the prolapse or surgical site.

Hard stools are one possible trigger, but so are diarrhea and other problems that make an animal strain. Treating every pink bottom with extra fiber can miss the real problem. A veterinarian should examine a first or recurring episode and decide whether digestive, urinary or other testing is needed.
These clinical examples show why a lump or protrusion deserves an examination. A photograph cannot establish the diagnosis, the depth of the prolapse or whether the tissue can be saved. An advanced, darkened case does not mean you should wait until your pet looks the same.
Full Rectal Prolapse in Dogs and Cats: It's an Emergency
Can a dog or cat prolapse heal itself? A small mucosal protrusion may retreat, but you cannot assume the problem has fixed itself. Do not wait to see how long a pet can live with it. A persistent prolapse needs immediate care; home reduction risks injury and delays treatment of the underlying cause. A rectal prolapse will not reliably fix itself, even if it temporarily retracts; the safe next step is veterinary assessment.
Let's say the worst has happened: You come home to find a "pink sausage" sticking out of your dog's butt. What do you do?
Your dog needs immediate veterinary treatment.
- Call the emergency clinic and leave promptly. Say that tissue is protruding from the anus, and mention any bleeding, vomiting, weakness or difficulty passing urine. If your regular practice is closed, its phone message may direct you to an emergency service.
- While arranging transport, prevent licking or dragging if you can do so safely. Ask the clinic how to protect exposed tissue. It may advise gently covering it with clean gauze moistened with plain sterile saline to keep it from drying. Do not scrub, squeeze or wrap tightly, and do not delay departure to gather supplies.
Do not use contact-lens disinfecting solutions, household antiseptics or human hemorrhoid creams. Do not put a finger or an object inside the anus or try to push the tissue back. Reduction is a veterinary procedure, often requiring anesthesia and assessment of tissue damage.
- Ask the clinic about food, water and any medicines before arrival because anesthesia may be needed. Tell them when your pet last ate; a recent meal is not a reason to postpone emergency care.
Use your existing secure carrier for a cat or small dog, with room to lie comfortably and without pressure on the affected area. For a larger dog, ask the clinic about safe handling and unloading. A frightened, painful pet may bite even when normally gentle. A replacement carrier is useful for future trips, but buying equipment must never delay this visit.
Risk Factors for Prolapse
| Tell the clinic | Why it matters |
|---|---|
| Diarrhea, hard stool or no stool | Digestive causes need different treatment. |
| Whether urine is passing | Urinary obstruction can look like constipation and is an emergency. |
| When the tissue appeared and whether it retracted | A brief episode still needs assessment; photos may help if safely taken. |
Persistent straining is the important clue. In puppies and kittens, severe diarrhea and intestinal parasites are particular considerations. Adult dogs and cats can also develop prolapse; age alone does not rule it out.
The Merck Veterinary Manual describes digestive, urinary and reproductive problems that can lead to prolonged straining. The examination therefore needs to look beyond the visible tissue.
If the veterinarian specifically recommends plain pumpkin as part of a fiber plan, use the quantity and product type they advise. Plain pumpkin is an optional food supplement, not a way to reduce a prolapse or a substitute for prescribed medication. Some pets need a different diet altogether.

Causes of a prolapsed anus in cats and dogs include problems that keep the animal straining. A kitten or puppy with diarrhea needs assessment of both the prolapse and its trigger. Important possibilities include:
- Severe diarrhea, including illness associated with intestinal parasites.
- Constipation, colitis, a rectal foreign body or a mass.
- Urinary disease or difficult labor that causes prolonged straining.
Repeated litter-box visits can look like constipation when a cat is actually having trouble urinating. Tell the clinic whether you have seen urine, not just whether the cat has visited the tray. Repeated straining with little or no urine needs emergency attention.
For ongoing stool problems, your vet can help distinguish constipation in dogs from diarrhea or obstruction. If the main sign is dragging the rear with no protruding tissue, scooting has several possible causes. Neither guide replaces an examination when tissue is exposed.
Treating a Rectal Prolapse in a Dog or Cat
The photographs illustrate appearances, not a treatment you can copy at home. PetMD’s veterinarian-reviewed guide estimates $2,000 to $6,000 for surgery to repair rectal prolapse in a dog. This is a broad published estimate, not a local quote or a price for every case. Simple reduction and a suture differ from removing damaged tissue or a colopexy for recurrence. Ask your clinic for a written estimate specifying anesthesia and surgery, tests, medicines, hospitalization and rechecks.
The vet assesses the exposed tissue and your pet’s overall condition, then investigates the straining. A stool sample, examination of the rectum, blood tests or imaging may be appropriate depending on the history. Mention recent deworming, diet changes, diarrhea, constipation and urinary signs rather than assuming the problem is only at the anus.
I treated both a dog and a cat for rectal prolapses. Both had an anesthetic and the prolapsed tissue gently replaced.
- 1Viable tissue may be gently replaced under anesthesia.
- 2A temporary purse-string can help prevent immediate recurrence.
- 3Damaged tissue or recurring prolapse may need a different operation.
There is a risk of immediate re-prolapse, so a temporary purse-string suture may be placed to help hold the tissue inside. This is used when the tissue and circumstances are suitable; it is not the answer for every case.
Keep fresh water available as directed and clean bowls regularly. Additional bowls or a pet fountain may encourage a pet that prefers moving water to drink. Follow the feeding plan if the veterinarian recommends wet food or adding water to meals; a fountain does not correct dehydration that requires treatment.

This suture is exactly what it sounds like: It tightens the anus in the same way a drawstring closes a shoe bag. An opening remains for soft stool to pass. The veterinarian sets a recheck and removal date, often around five to seven days, according to healing and the underlying problem.
Stool consistency matters while the suture is present. Your vet may prescribe a stool softener such as lactulose and a specific feeding plan. Give the prescribed amount and call if it is difficult to administer; do not substitute a human laxative or enema.

Why the Discharge Plan Matters
Unfortunately for my feline patient, the client overlooked giving the lactulose, so the cat became very uncomfortable.
That cat needed further veterinary intervention with an enema before things could settle down. The experience illustrates why discharge instructions and scheduled rechecks matter as much as getting the tissue back into place.
When Further Surgery Is Needed
What happens if the purse-string suture does not prevent recurrence? The vet reassesses the cause and the tissue. A colopexy, which fixes part of the colon to the abdominal wall, may be considered for suitable recurrent cases. Damaged or dead tissue may instead require removal and reconstruction. These are different operations with different risks, so ask which procedure is proposed and why.
Recovery and Preventing Another Prolapse
Before leaving the clinic, ask for a written plan covering medicines, feeding, activity, cleaning, protection from licking and the next examination. Keep the emergency phone number with it. If someone else feeds or medicates your pet, make sure that person has the same instructions.
Set up a quiet resting area on clean, washable bedding. A familiar towel or blanket you already own may be sufficient; a washable waterproof blanket can protect the resting surface during recovery. It is bedding, not a dressing for the prolapse or surgical site.
How to Manage Your Pet's Stool After Treatment
Ask the vet what stool consistency to expect and when your pet should next defecate. A plan for constipation differs from one for diarrhea. Do not independently add fiber, switch several foods or change the laxative dose because the first stool looks different. Report repeated straining, inability to pass stool or renewed protrusion promptly.
If the veterinarian specifically recommends plain pumpkin as part of a fiber plan, use the quantity and product type they advise. Plain pumpkin is an optional food supplement, not a way to reduce a prolapse or a substitute for prescribed medication. Some pets need a different diet altogether.
Hydration and Follow-Up During Recovery
Keep fresh water available as directed and clean bowls regularly. Additional bowls or a pet fountain may encourage a pet that prefers moving water to drink. Follow the feeding plan if the veterinarian recommends wet food or adding water to meals; a fountain does not correct dehydration that requires treatment.
Watch each toileting attempt during early recovery. Contact the clinic for renewed swelling or protrusion, bleeding, worsening pain, poor appetite, vomiting, marked lethargy or difficulty passing urine or stool. Do not wait for the scheduled suture removal if something changes. The underlying illness and any complications determine recovery time.
Recurrence and scheduled rechecks are part of the follow-up care plan. Even a briefly protruding ring of tissue needs examination: safe transport protects tissue while you get help, whereas home reduction can damage it.
Rectal Prolapse Questions
There is no safe waiting period to calculate at home. Exposed tissue can develop serious tissue damage, and the condition needs urgent treatment. Prognosis depends on tissue viability, the underlying cause and prompt veterinary care; ask the treating veterinarian about your dog’s case.
PetMD gives a broad estimate of $2,000 to $6,000 for surgery in dogs. Your pet may need a different procedure, and local fees, hospitalization and treatment of the underlying illness affect the total. Ask for a written estimate covering anesthesia and surgery, diagnostics, medicines and follow-up. Tell the clinic about financial constraints when you call, without delaying assessment.
A swelling beside the anus, an anal-sac problem or other protruding tissue can look alarming without being the same condition. Possible intussusception, in which one section of bowel telescopes into another, is an important veterinary distinction. Do not assume a lump is a hemorrhoid or try a home test: a veterinary examination is needed.
Final Thoughts
Monitor your pet for straining, and get help if things aren’t right.
Promptly addressing straining and following the recovery plan can reduce the chance of complications. A prolapse that briefly disappears still deserves a call to your veterinarian.
