Itching and skin conditions can be caused by many things: environmental allergies, food intolerances/sensitivities, fleas, and food allergies.
If environmental allergies are the cause it can help to wipe your dog often with a wet towel, give them a foot bath, and regular baths with a dog shampoo to remove allergens from their skin and coat. (avoid oatmeal shampoos) Giving Your Dog a Foot Bath https://www.homeskooling4dogs.com/bathes
Some dogs are hypersensitive (allergic) to a single flea bite which can result in itching and suffering from flea allergy dermatitis. If this is the source you will need to eliminate fleas from your environment. https://www.homeskooling4dogs.com/fleas-ticks
It’s possible that is related to a food allergy, but food intolerance or sensitivity is more common than a food allergy. Food allergies reflect a more immediate immunological response whereas food intolerances/sensitivities build up over time with exposure to offending ingredient(s). Food intolerances/sensitivities can manifest in gastrointestinal issues, chronic itching, chronic gas, chronic skin, and ear and foot infections.
Allergy reactions show up in allergy blood test as antibodies (IgE and IgG). Food intolerance/sensitivity is done by testing a dog’s saliva for a differing set of antibodies (IgA and IgM). I have used the NutriScan test on both of my dogs and plan on testing all future dogs to be proactive with health issues.
Food intolerances/sensitivities to a main ingredient like chicken or lamb, or something small in the food like salmon, menhaden, or herring oil, peas, lentils, quinoa, etc.. This is one reason to rotate regularly what we feed dogs. It is essential to identify and eliminate any food from the diet that can create intolerance. NutriScan takes the guesswork out of rotating and eliminating differing foods through food trails. I have used and recommend food sensitivity & intolerance test from NutriScan. With the NutriScan kit you collect saliva with a small cotton dental rope. You can do this at home or at the vet’s office. Then ship the kit back to Hemopet for testing.

Natural Skin Tonic – This lemon-based tonic not only repels fleas, it works as a general skin toner for itchy pets. Thinly slice a whole lemon, including the rind, and steep it overnight in a pot of boiling water. The cooling water draws out d-limonene, vitamin C, and other healing ingredients found in the whole lemon. The next day, sponge it on your dog’s skin and let the solution air-dry.
