Skin Infection on Dog's Lower Back
Frenchie about 7 years old female itches horribly until the skin bleeds. the skin has a large hairless area on the lower back. Hairless skin area has large brown patches, with some dark brown spots and raised areas.
Editor Thoughts Regarding Dog Mange
Based on the described symptoms and their localization to the lower back, the following are the more likely causes:
Flea Allergy Dermatitis (FAD): This is one of the most common reasons for intense itching focused on the lower back. Even if fleas aren't visible, a single bite can cause a severe reaction in a flea-allergic dog. The intense itching, coupled with the described skin changes, fits well with FAD.
Bacterial and/or Yeast Infections: These secondary infections can be a result of the primary irritation (like from fleas) or due to the dog's excessive licking and scratching. The described darkened skin, raised areas, and light brown patches can be consistent with chronic infections or inflammation.
Environmental Allergies (Atopy): If the dog has been in contact with allergens like grass, the lower back can be a primary location for symptoms, especially if she frequently lays on these allergens.
Contact Dermatitis: This might be lower on the list but shouldn't be ruled out, especially if the dog has been exposed to new bedding, cleaning agents, or other environmental factors.
While mange (either sarcoptic or demodectic) is a potential cause of skin issues like these in dogs, the specific localization to the lower back makes it a bit less likely. However, it should still be considered, especially if other causes have been ruled out.
That being said, while I can provide some gueses based on the information you provided, a hands-on examination by a veterinarian is essential to accurately diagnose the issue. They can perform specific tests, like skin scrapings, cultures, or allergy tests, to pinpoint the cause and prescribe the most effective treatment.
