What breed is your dog? The larger the dog, the shorter they live, so if it is a large breed, this could simply be aging. However, it is strange that there is a random concentration of baldness on his tail. I'd see a vet to be safe.

Mange mites and flea infestations are common in this area of the dog, they need to be identified by a Vet and the correct treatment administered for which ever problem it is.

It could also be other things like dermatitis, your Vet will help you with this.

It could be allergies; you need to consult a Vet, before the dog gets really bad. Sand Fleas can also cause that; so can Mange.

Take him to a Vet for a skin scraping and/or lab work to find out why this is happening. Could be mange, a flea allergy, a thyroid condition? Too many possiblities. A Vet will need to examine your dog, people here can only guess and trying to fix it according to what you think is the best guess could be harmful to your dog. Hope your dog will be okay.
