My Dog Ate a Tampon

Do NOT Induce Vomiting
The danger here is intestinal blockage, not poisoning. Tampons expand when wet and can obstruct the bowel. Do not try to make your dog throw it up -- a tampon can get stuck in the esophagus on the way back up. Call your vet for guidance.
If your dog ate a tampon, the issue is mechanical -- not chemical. Tampons are not toxic. They are not going to poison your dog. The danger is that a tampon is designed to absorb liquid and expand, and it will do exactly that inside your dog's digestive tract. A tampon that expands in the stomach or intestines can cause a partial or complete blockage, which prevents food and fluid from passing through. This is a surgical emergency if it does not resolve on its own. Here's what to do right now.
What to Do Right Now
- Do NOT induce vomiting. A tampon can lodge in the esophagus during vomiting and create a choking emergency. The string can also wrap around internal structures.
- Figure out what was eaten. Was it used or unused? With or without applicator? One tampon or multiple? Used tampons are softer and more compressible. Unused tampons expand more and pose higher blockage risk. Plastic applicators add another foreign body concern.
- Call your vet. Describe your dog's size, what was eaten, and when. Your vet may recommend monitoring at home or coming in for an x-ray.
- Feed your dog a normal meal. Some vets recommend feeding a bulky meal (like bread or pumpkin) to help cushion the tampon and move it through the digestive tract. Ask your vet first.
- Monitor every bowel movement. Check your dog's stool for the next 3 days. You are looking for the tampon or pieces of it to pass through.
- Watch for warning signs of blockage. Vomiting, bloating, inability to defecate, loss of appetite, lethargy. These are red flags.
Why Tampons Are Dangerous for Dogs
Tampons are specifically engineered to absorb moisture and expand. That is the entire point of the product. Inside a dog's digestive tract, a tampon will absorb gastric fluids and swell to several times its dry size. This creates a soft but bulky mass that may be too large to pass through the narrow sections of the intestines -- particularly the pylorus (exit from the stomach) and the small intestine.
A complete intestinal blockage is life-threatening. When nothing can pass through, the tissue upstream begins to die from pressure and lack of blood flow. Bacteria from the gut can leak into the abdomen, causing peritonitis (infection of the abdominal cavity). Without surgery, a complete obstruction can kill a dog within 3-5 days.
The tampon string adds another risk. If the string catches on something internally while the tampon moves through the digestive tract, it can cause the intestines to bunch up like fabric on a drawstring -- a condition called linear foreign body obstruction. This is particularly dangerous and requires immediate surgery.
How Much Is Too Much
Even one tampon can cause a blockage, especially in smaller dogs. Here is the risk breakdown by dog size:
- Small dogs (under 15 lbs): High risk. A single tampon -- used or unused -- can cause a blockage in a small dog. Call your vet immediately. An x-ray is strongly recommended.
- Medium dogs (15-40 lbs): Moderate risk. Many medium dogs will pass a single used tampon, but an unused tampon that fully expands is a real concern. Call your vet and monitor closely.
- Large dogs (40-70 lbs): Lower risk but not zero. A single tampon will usually pass in a large dog. Monitor bowel movements for 3 days. Call vet if any blockage symptoms appear.
- Giant breeds (70+ lbs): A single tampon is unlikely to cause a blockage. Monitor stool for passage. Multiple tampons, an applicator, or an unused tampon still warrants a vet call.
Used vs. unused matters. A used tampon is already partially expanded and softer -- it is more compressible and more likely to pass. An unused tampon that expands for the first time inside your dog's stomach is the highest-risk scenario.
When to Call the Vet
Call your vet right away if:
- Your dog is small (under 15 lbs) -- do not wait for symptoms
- Your dog ate an unused tampon or multiple tampons
- Your dog ate the plastic applicator
- Vomiting -- especially repeated vomiting or vomiting after eating/drinking
- No bowel movement for more than 24 hours
- Straining to defecate with no result
- Bloated, distended, or hard abdomen
- Loss of appetite lasting more than 24 hours
- Lethargy, weakness, or whimpering
- Your dog stops drinking water
If your dog is still eating, drinking, and having normal bowel movements after 72 hours, the tampon has likely passed or broken down enough to not cause problems. But if you have not seen evidence of it in the stool and your dog develops any symptoms, get to a vet.
