Causes of scabs on the back near the tail

Skin allergy

If your dog is continuously biting at one place, your pet may have skin problems. Signs of skin allergies are the following:

External parasites

Some dogs are receptive to flea bites. Flea allergies often cause bumps, scabs, redness, and itchiness in dogs. Although you keep your dog clean and have never seen a flea on your pet, a few could be hiding in the fur of your dog or yard and can cause infections in your pet. Whenever you note skin problem in your pet, find the fleas in your house and try to get rid of.

Flea collars are available in the market that keep your pet safe from these harmful pests and many skin problems caused by fleas. Before buying any collar for your pet, ask your vet first.

Mites are also external parasites that can cause similar skin problems in your pet. Demodex mites cause hair loss and redness by living in the hair follicle, but affected dogs aren't usually very itchy.

Scabies mites are not very common but can cause many skin problems such as itchiness and lesions. These are contagious mites to other pets and even humans.

Fungal infections are also common in pets. Ringworm is a fungal infection that may lead to hair loss, red skin, bumps, scaly skin, scabs, and sometimes itchiness. It is also infectious to other pets and humans. You can use lime sulfur dips to treat this fungal infection in a very effective way.

How to diagnose scraps

Diagnosing skin infections such as scabbing can be easy or very difficult, depending on the situation. Vets should follow a protocol to make sure something isn't missed.

Physical Exam: 

The best and simple way to diagnose skin lesions and scabs on the dog is a comprehensive examination. Your vet may find fleas or other external parasites during your pet's physical examination and can see the root cause.

Skin Scraping: 

Skin scraping is the microscopic examination to look for external parasites. Some mites, such as Demodex mites, are easy to find with a skin scraping technique. Few mites, such as scabies mites, are difficult even with a skin scraping.

Fungal Culture: 

If the evidence collected from skin scraping is not enough, a fungal culture is used to find the root cause. Hair or skin samples are positioned in fungal culture media for a few days to see the fungal growth models.

Bacterial Culture: 

Dogs may also develop resistant bacterial skin infections that don't respond to most antibiotics. A bacterial culture can identify the bacteria and recommend which antibiotic drug has the best chance to get rid of it.

Cytology: 

Skin cytology also helps to diagnose and treat skin disease. Collect an exact piece of tape and examine it under a microscope for bacteria and yeast. Skin problems are secondary; identifying the organism causing the skin allergy is primary, so you can choose medicine for the secondary pain by identifying the problem's primary source.

Allergy Testing

The best way to test the allergy is to inject allergens into the skin to see the causes of reaction. Veterinary dermatologists do skin testing in most cases, including blood testing.
