My dog's allergies cause recurring skin spots. What can I do?

Updated On September 23rd, 2025

Pet's info: Dog | Boxer | Female | spayed | 1 year and 6 months old | 40 lbs

Hi I have a two year old boxer who has always had trouble with allergies and recently they seem to be worse. A week ago she broke out with these spots all over her body. With some allergy medicine and a bath they went away a few days later. She has now broken out again with the same spots and I don't know what I can do to stop this from happening. Any ideas? Thank you!

Oh poor girl! Thanks for letting us help you today! The first thing you should know is that you are not alone. It really comes down to figuring out what is causing her allergies so that they can be treated or the specific allergen avoided. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively! Good luck with Ellie!
