Dog peeing in house after allergy shot. Is it a steroid side effect?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 5 years and 11 months old | 50 lbs

My dog has some awful allergies! She itches&bites so bad that at one point she looked as if she had mange! She bleeds, loses hair, licks her under belly until its red, sticky&then turns somewhat crusty. So we took her to the vet&he said it was some type of allergy coming into the area. Periodically, he gives her an allergy shot(not sure what it's called)&it seems to help a bit. After she gets the shot, she has no control over her bladder. She has never peed in the house. Why is this?

Hello there. While there are several types of shots that can be called allergy injections, it sounds like Uno might be receiving a steroid injection to help with her itching. Some common side effects from steroids are excessive hunger and excessive thirst. The increased water intake can increase urination and come sometimes lead to accidents in the house. While steroids can be a very effective treatment for allergies, there are other treatment options that you can discuss with your veterinarian.
