What causes black scabs, bleeding, and hair loss on my dog's ears?

The black scabs may be due to her itching at her ears a lot. The inside of Zeda's ears look red, and she may have an ear infection, or ear mites that are causing her to itch. The black spots can also be a sign of an ear infection or ear mites. She needs to be seen by a veterinarian soon. The vet will be able to look down her ears with an otoscope, and take samples if there are signs of infection, so that she can be treated with the correct medication. This will hopefully provide Zeda with some relief.

This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria or fungal). A check up, appropriate disinfection and possibly antibiotics or antifungal meds (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can possibly be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar is useful as well to avoid any scratching (as you have used).

It's probably an ear infection, often it cannot be seen from the outside. Ear infections are very common in dogs, it is usually caused by either yeast or bacterial disease. the treatment is usually simple and straightforward, you will have to take Shadow to the vet and get the ears checked, then a prescription ear drops will be prescribed according to the infectious agent.

I would recommend doing testing on the ears to find out what is causing the scabs. If your pet is outside a lot, then flea bites are possible and it is recommended to purchase flea bite repellent at your local pet store to start, followed by topical triple antibiotic to get the scabs to heal. If your pet is kept mostly indoors, two common causes of this are demodexx mites or a yeast infection. Also another condition called ear margin vasculitis could be the cause. Ear margin vasculitis is a spontaneous condition where the vessels at the ear tip margin become inflamed creating a scabby appearance to the skin. Since all 3 of these look very similar it is important to get testing done in the form of a skin scrape/cytology and/or skin biopsy because each is treated so differently and it takes out a lot of the guess-work. Therefore scheduling an appointment with your vet is needed for proper diagnosis and treatment.

It looks like your dog could have a bacterial and/or a yeast infection. Have him examined by a vet for treatment. Your vet can prescribe medications to help. Your vet could also test his thyroid level to make sure he doesn't have a thyroid issue. You could also bathe him with a medicated dog shampoo and see if that helps.

This appears to be some sort of topical dermatitis. It can be caused by an underlying allergy, a bacterial infection or a fungal infection. You will most likely need to put a topical medication on the sores to help them clear up. You can try some triple antibiotic ointment at home and see if that helps. If not, you will need to take Chico to see your veterinarian. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
