Welcome! I am Dr. Altman, a licensed veterinarian and happy to answer your questions today.
I am so sorry no one has yet to assist you yet today. Unfortunately anal glands are the most common cause of the symptoms you mentioned including scooting, licking
, chewing, sitting abruptly and do need to be expressed regularly in some dogs to prevent recurrence (every 1-2 months). A groomer or a veterinary technician is able to do this for you to avoid a veterinary exam fee. Below is some information on anal gland issues in dogs:
The second most common cause of this chewing and irritation in this area is a flea allergy dermatitis
. Just one flea bite can cause a dog who has allergies quite significant distress for an extended period of time so purchasing a flea product such as frontline or advantage at your local pet store is advised as well.
The area you describe and her age makes mites much less likely. If it were mange this is a general itching and hair loss not localized to the tail base area and demodex (the other dog mite) is only seen in young dogs typically < 1 year old
The last cause of chewing the area which again is not as common as the first two is a food allergy. Dogs are most commonly allergic to the proteins in their foods so if the top two are not found to be an issue this would be the next step. Doing a food allergy trial using a food that is specifically for this purpose, which is where the proteins are broken down beyond the point where the body recognizes the protein as beef, chicken
, fish and monitor for improvement in signs. These foods are prescription only and include: royal canin h/p (hydrolyzed protein), hill's z/d ultra
