My dog ate tampons and threw up. Should I worry about a blockage?
Hello there!
Tampons absorb fluid, so when ingested, they can swell in the intestines and cause a blockage that requires surgery. This could affect any size dog, but as Hershey is a large breed, she has a better chance of being able to pass the tampon without needing surgery. This is good news!
The signs of her having an intestinal obstruction that requires medical or surgical attention would be: Not interested in food, vomiting, diarrhea, lethargic, being reclusive (like laying in a corner by herself)
I am not alarmed that she has vomited once, but keep an eye on her. If she starts to show other signs that I mentioned, take her into her vet. They will recommend x-rays to check for a blockage in the intestinal tract and bloodwork to check for infections and anemia that can result from a blockage. Then they will either recommend medical intervention, which may include fluids, antibiotics, a high fiber diet, and enemas, or surgical intervention, which may include cutting the intestine to remove the tampon or having to remove a piece of intestine if there is tissue damage.
Again, this is worst case scenario. As she is still eating well, defecating normally, and behaving normally, I think home monitoring is absolutely fine for now considering she is such a large dog. Next time she vomits, try to remove it from her before she can eat it again- I realize this is easier said than done. :)
I hope this is helpful! Thanks for using Petco Pet Education Center, formerly Petcoach!
