Online vet, Dr. Marie

Dr. Marie replied:

It's always hard to answer skin questions without actually seeing an animal but I will do my best to see if I can help.

If the hair loss is extending from the middle of her back down to her tail then by far the most common reason for this is an allergy to fleas. Some animals are so allergic to fleas that even one flea bite can set them off. If she is not on a prescription strength flea product such as Advantage, Revolution or Frontline then I would recommend doing this.

There are also some diseases called endocrine diseases that can cause hair loss and darker skin. One common one is hypothyroidism. Another is Cushing's disease. Both of these are treatable conditions.

Sometimes skin can turn dark if there has been an infection (either bacterial or yeast) present for a long time. If there is an infection you should notice either some odor, or some greasiness to the skin or possibly some crusts or pustules.

It sounds like a vet visit is a good idea!

Dr. Marie.
