My dog has chronic skin issues. What are the underlying causes?

Updated on September 23rd, 2025

Pet's info: Dog | Catahoula Leopard Dog | Female | spayed | 50 lbs

My dog has a few puss filled red bloody bumps on the sides of her body. Along with a ton of textured bumpy skin. It is making her look unhealthy and I am worried. The vet has tried at least 5 different types of medicine but nothing completely fixes the problem. Please help.

There are four main causes of persistent skin issues and you must figure out the underlying cause to address the problem. The causes are: flea allergy, food allergy (this needs to be ruled out with a hydrolyzed diet), environmental allergy or hypothyroidism.
With out any further information, it’s hard to know how to advise next steps. If your veterinarian is not comfortable with treating chronic skin conditions, find one who is.
I recommend to rule out fleas with a product like Simparica. I rule out food allergy with a diet called Ultamino. Hypothyroidism is a blood test. Environmental allergies are unfortunately very common and also more complicated but they can be determined with a blood test as well.
I hope this is helpful and please feel free to post any additional questions.
