Why does my dog have chronic skin allergies, licking, and black spots?

Updated On September 23rd, 2025

Pet's info: Dog | Dachshund (Wire Haired) | Male | neutered | 10 years and 11 months old | 22 lbs

My dachshund has had this skin allergy for over 6 months. He constantly licks bites and scratches his paws legs belly ears and face. He has these black specks that appear to be tar like that come out of the hair follicle. Some on belly look like black heads. I’ve been Bathing him twice a week with medicated shampoos. I bring him to a holistic vet and she has tried everything from acupuncture to laser to every herb and supplement. He is on a raw food diet. He also had a fecal transplant.

I hate to hear this is happening to Halo. In general, those spots on Halo could be several things including allergies to fleas, allergies to something in the environment, food allergy or endocrine disease. Each one of these problems is detected and addressed differently and I recommend to discuss with your veterinarian which one to start hunting down first. Parasites are often ruled out with an oral medication like Simparica. Food allergy is best ruled out with a diet trial using a hydrolyzed protein. Endocrine diseases are detected with blood work. Environmental allergies are a little more difficult to detect but a response to therapy or a blood test can give an indication. Once you figure out and address the underlying cause, the lesions should not come back. There are a couple things you can do at home and they can help but they may not address the underlying cause. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. Also protect the area from trauma by having Halo wear an elizabethan collar at all times. I hope this helps and please feel free to post any additional questions.
