As veterinarians, we should not give advice without seeing patient. As is repeated here often, there is not just one fix-all. But I can offer some pathways. In these chronic dogs, we can see secondary assaults on the derm layers, yeast, staph, pigmentation, lichenification, thus Rx can depend on how much skin is affected. We also look at the TCVM pattern, dampness, dryness, blood deficiency and more. Medicinals that affect the immune system are valuable, mushroom, nettles. Skin protectants that reduce the allergen load can be beneficial and bought from general practitioner. I also suggest to my caretakers to use light blankets, sheets over bedding, areas where they rest. These can be washed more frequently to also help reduce the allergen load. The veterinary dermatologists say to regard the patient/dog as being covered in powdered sugar (or pollen) when it comes from outside, which can concentrated in resting areas. Once the pollens/ allergens touch the skin, the body's immune system sets up the histamine response within feet, axillary/groin, perineal regions and ears. Itching results, or we call it corn-cobbing. Diets are supportive and some maybe also create hypersensitivity responses. We use the TCVM exam as well to determine type of diet. The no-grain or grain free diets have created concern for cardiac disease in some patients, please be aware. For some it may mean a homemade diet. Balance-It is a website where it can be formulated for complete nutrition. Another student here, Dr. Constance Di Natale has a very special interest and teaches dietary concerns for our patients. Her practice is in Florida. I highly suggest that an integrative veterinarian also examine the skin. There are many groups, AHVMA, VBMA (veterinary botanical), CIVT, Chi University, AAVA, IVAS, where you can look for DVMs in your geographical regions. Lastly, my cases of skin disease are some of the more frustrating and complicated ones I see. To manage, not cure is our goal in most, unfortunately. If your friend has this in mind, it may help in some small ways.
