My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.
Dogs frequently eat things they shouldn’t. If your dog ate it in the last hour and a half then you can try to get your dog to vomit the tampon back up. This is important because tampons are designed to swell and if it swells inside the stomach, it may require surgery to remove. You can induce vomiting with hydrogen peroxide 3%. Instructions on dosage can be found here:
If it has been longer than an hour and a half, then you will need to watch your dog for abdominal pain, constipation or difficulty having a bowel movement, not eating or drinking, or dry heaves. If your dog develops any of these symptoms that would indicate an intestinal obstruction and immediate vet care is needed to remove the tampon. Read more on that here:
A large dog may pass a tampon with little difficulty, but smaller dogs may have serious problems so please keep a close eye on your dog and be sure the tampon is safely out of booboo's system. The good news is that a used tampon does not swell as much as an usused tampon.
