Q. For the last couple of years around this time of year my long haired dachshund has been getting hot spots by his tail and chewing himself raw
A. The location of these hot spots leads me to believe that they could be caused by flea allergies. I would highly recommend having your pet placed on a veterinary recommended flea and tick preventative like Vectra, Nexgard, or Bravecto. If you have already taken this step then your dog may have environmental allergies that are seasonal. Some dogs need to be placed on daily allergy medications during these seasons to get them through without hot spots. Others require steroids to reduce inflammation and itching. Consider working with a veterinary dermatologist to resolve this issue or look into allergy testing.
