Hi, I can help you with your question today.

Chewing the tail and rear end could be due to anal gland impaction or infection. The pressure in the anal sacs can cause discomfort and dogs often scoot or lick when this happens.

Expert:  brisadog replied 1 year ago.

Aside from that, now tat she is licking her front legs as well, there are a number of different things which might cause this.

Expert:  brisadog replied 1 year ago.

Environmental and food allergies are possibilities. Even without a change in diet, she may have developed a new allergy (this can happen at any age).

Expert:  brisadog replied 1 year ago.

She may also have a contact sensitivity - any new detergents, blankets, etc?

Expert:  brisadog replied 1 year ago.

Fleas are only one parasite which might cause itching. We can also see sarcoptic mange, for example, causing itching.

Expert:  brisadog replied 1 year ago.

Skin infection (pyoderma) can also cause itching. At this point, I recommend having her evaluated by your regular vet. I would start with a physical exam and check her anal glands.

Expert:  brisadog replied 1 year ago.

They can do a skin scraping to look for mites, and a cytology to look for bacterial or fungal infections.

Expert:  brisadog replied 1 year ago.

If everything is normal, I would start a short course of prednisone to relieve the itching, and try a hypoallergenic diet.
