My dog had a small little bump on her back that was kinda pussy so I popped It and white puss came out but the bump is still there. She also has a small rash under her back legs near back end that’s kinda reddish/blotchy.

Thanks for using PetCoach! This is most likely a postule or focal infection. Usually there is going to be a residual bump even after drainage. If it continues to be present in the next week or so, have her evaluated by your veterinarian for further assessment. The rash may be present due to allergies, especially if causing her itchiness. 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!
