Thank you for contacting JustAnswer with your questions. I'm sorry Rory is so itchy.

-Veterinary Experts are able to provide general medical advice. We are NOT able to provide a diagnosis or prescribe medications. I can help you to determine if a veterinary visit is needed or if it seems reasonable to monitor and treat at home.
-You may be automatically prompted to consider a phone consultation for an additional fee. Unfortunately, I am not able to provide phone consultations. If you would like to continue the chat, just hit decline. If you would like a phone consultation, let me know and I will disconnect so you can speak with another Expert.
-I will do my best to respond to you as quickly as possible. Sometimes, my response may be delayed if I am helping other customers as well. I assure you that I will get back to you as soon as possible to answer all of your questions.
I'd like to ask you some questions so that I can provide the best advice possible
-Has Rory had issues with itching in the past?
-Is Rory losing hair?
-Is there any scabbing or crusting of the skin?
-Can you send a picture of what is happening to her skin?
Poor baby. Is this all over her body?
-So there is a patch on the other side that is healing?
-It she had mites (mange) it would not be likely the area would heal up even if she was not chewing at it, since the mites destroy the hair.
-Severe conditions can cause the skin changes you are seeing.
-Allergies can occur to food or substances in the environment. Dogs can develop allergies to food even if they have been on the food for months to years. Typically, it is the protein in the food they are allergic to. Itching and scabbing will typically occur year-round with food allergies. Feeding a prescription hypoallergenic diet for 12 weeks can help to determine if food allergies are present. Over-the-counter limited ingredient or skin support diets are not likely to be helpful as there is a lot of cross-contamination that has been proven to occur with these diets.
-Environmental allergies, to pollen and dust mites, are also common. These tend to get worse in certain seasons. Sometimes, they may not change if the allergen is always in the environment. Generally, these allergies are diagnosed by the response to treatment. Steroids may also be helpful to decrease itching, but can have some serious side effects like thinning of the skin, elevated liver value, increased drinking, increased urination, panting, and hunger. Steroids, Apoquel, Cytopoint, and hyposensitization shots are all possible treatments for allergies.
-Environmental allergies can be helped dramatically with twice-weekly bathing in an oatmeal shampoo. Wet the fur with lukewarm water, lather well, allow the shampoo to stay on the fur for 5-10 minutes. Rinse the fur very thoroughly to be sure all soap is removed.
-Fleas can cause itching and scratching. Dogs can be allergic to flea bites, so it may not take very many to cause severe itching. It is best to be sure you are using a flea treatment that kills the adult, egg, and larval stages of the flea even if you are not seeing fleas.
-Skin mites can cause very intense itching. A skin scraping is needed to find the mites. Some types of mites can be very difficult to find, so your veterinarian may recommend treating mites even if they are not able to find the little critters.
-Fungal and bacterial infections of the skin can also occur. Bacterial infections can be diagnosed by getting an impression of the area and looking at it under the microscope. Fungal infections require a special culture of the fur.
-It is not possible to say which of the causes, or possibly other causes, is what is bothering Rory.
-I would recommend that you apply a flea medication as described above. Make sure that the flea medication is labeled to kill all life stages. Only use flea medications labeled for dogs of her size, and age. Bathe her twice a week as described above. Make sure to wait at least 3 days after applying flea medication to bathe. You can also try antihistamines, although they are only effective in about 25% of allergy cases. Typically, I start with Benadryl. This can be dosed at 1mg/lb (5mg for her size) three times daily.
-Adding fish oil or omega fatty acids to her diet may help as well.
-If the itching is not improving within 3-5 days, I would recommend that you have her evaluated by his veterinarian to see if other treatments may be helpful.
-Oh, please please do not use a grain-free diet.
-90% of dogs are allergic to the protein source in their diet. Grain-free diets have been associated with the development of heart disease even in breeds that do not commonly develop heart disease. Restarting a grain diet improves heart function. It is not known why this occurs, but I DO NOT recommend grain-free diets unless the dog has a proven allergy to a grain source.
Do you have any questions?
-It doesn't look like the hair is regrowing in the area, is it?
-If that is the case, mites are still possible, since it is not really healing.
-I think you should make an appointment with the veterinarian as soon as poosible.
