My dog's flea allergy causes itchy lumps. What treatments work?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 3 years and 3 months old | 7 lbs

I know she has a flea allergy, but under the skin behind her ears are to semi soft inch long lumps. They same to he itchy as well because every time I touch them she presses her head harder for more pressure. I've tried advantage, revolution, frontline. Many different flea shampoos and powders, apple cider vinegar and citronella and nothing works. I don't know what to do now.

Flea allergies can be very difficult to manage, I completely sympathize with your frustrations and below I will try to suggest some more tactics for you to employ;

Treat your home for fleas as fleas actually spend more of they life cycle off of your dog then on it

3 solid months of topical treatment to end the flea life cycle

Skin health supplements such as vitamin e and fish oils
