Why is my dog so sick after anesthesia-free dental cleaning?

Updated on September 23rd, 2025

Pet's info: Dog | Pembroke Welsh Corgi | Male | neutered | 1 year and 5 months old | 36.5 lbs

Hi - i have an one year old Corgi, who did a dental cleaning (Anesthesia-free) yesterday. After taking him home, he started vomitting more than 10 times, sometimes with blood. He's having bloody diarrhea since this morning. I've taken him to the vets nearby and they're still running the fecal exam. Im wondering how come a basic dental cleaning could cause such a terrible situation? My dog has totally lost appetite and not willing to take medication with his favorite cheese coated.

I'm sorry to hear that Hammer is not feeling well. Dental cleanings are typically performed under anesthesia in petd because they can be uncomfortable and sharp objects are used to remove tartar in the mouth. Depending on the level of dental disease, it is possible that the dental cleaning was uncomfortable for him and could cause a great deal of stress if significant restraint was required. Stress can cause stomach upset including bloody diarrhea. Given the severity of his signs, I am glad that you had him seen by veterinarian. If he does not improve with the prescribed treatment, I would recommend scheduling a recheck examination. I would also recommend checking with your veterinarian about ways to manage dental health in the future.
