My 3 month pup is losing hair on his back pretty badly, and I was wondering what I could do to stop it? He also has, like, little red bumps, and I don't know what's causing it.

It may be potentially difficult to treat depending on the cause. Things like mites, fleas, bacterial infections, ringworm or allergies could all look like this and cause hair loss. Unless you discover the underlying cause, you won’t be able to stop it. A visit to your veterinarian would get you the answers the fastest. The doctor can preform a few simple tests to find out if it’s mites, ringworm or fleas. They can also provide antibiotics and medicated shampoo to treat the bacteria. If you want to try home care first, you should wash the area with a hand soap once a day. Rinse well. You can apply a dab of coconut oil to the lesions and rub in well. You must keep Tyson from licking it! If you use a product like Simparica or Nexgard, it will treat fleas and elimate that as a cause as well. If he’s not getting better or if he is getting worse, he needs to see the veterinarian. I hope this is helpful and please feel free to post any additional questions.
