Why are my dog's skin lumps returning after steroid treatment?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 4 years and 2 months old | 55.5 lbs

My dog has had lumps on and off for some time-on head sides and back mostly. She was treated w a steroid and Benadryl which seemed to help. She has since been off for a few weeks and they are starting to return. Also switched foods. What could be causing this?

I would guess she's being exposed to something that is still causing an allergic reactions. Unfortunately, this could be anything from food to fabric softener. Before changing everything, I would recommend to take her back into her vet and likely put her back on steroids and for a longer course. Sometimes the immune system can be stubborn to calm down. Take a photographs of your old food ingredients as well as your new food ingredients for comparison. I would recommend ruling out diet issues first if the allergic reaction comes back for a 3rd time. I hope this helps!
