Hair loss could be several things including allergies, skin mites, flea bites, ringworm (which humans can get) or a bacterial infection. 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 her diet to something like Royal Canin or Nutro as they are aimed at skin health. You can wash the lesions with soap once a day and rinse well (don't wash her whole body, just those spots). Protect the areas from licking or scratching. If they don't start looking better within about a week or if they get worse, have Marley examined by the veterinarian who may prescribe medications. Best of luck and please feel free to post any additional questions.

Hi, thanks for using PetCoach!

Possible causes for hair loss on the tail are: fleas, demodex mites, ring worm or a bacterial skin infection. I would have him on Nexgard to cover for fleas and demodex. You can try a medicated shampoo, bathe 2 times per week and leave the lather on the area for 10 mins before rinsing. If there is no regrowth or improvement in 2 weeks I would have your Vet examine the area. There is a scent gland on the tail and hair loss can occur at that location but I usually see that in older dogs.

Also you can always post a picture here. Good luck!

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 eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any licking.

Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Glad you asked! Definitely looks to be a problem. This problem could be related to any number of skin diseases including nutrition, parasites, minor skin infections, or allergies. Depending on whether this area is itchy or not, this may determine what kind of tests your veterinarian may run to narrow the problem down. In any event, waiting a week or so won't change much, but you should get an appointment on the books with your veterinarian as soon as financially possible. The sooner we find out what's causing it, the sooner we can treat it appropriately. May require medication, bathing, or anti parasite products to help out the condition. Good luck and thanks for reaching out. Steve Popish, DVM.
