A. Flaky and itchy spots of skin can be caused by a number of things including food or environmental allergens, or even allergic reactions to external parasites. Checking for fleas and ticks is a good first step, and if they are seen, treating for them with a monthly preventive as well as cleaning the environment can help. Food allergies are also common, and can occur with ingredients such as wheat, corn and soy products. If you suspect a food allergy, switching to a sensitive skin or grain-free diet may help. Environmental allergens can also cause itching and redness due to dusts, grasses and pollens. A daily allergy medication (your vet can give you the dosage depending on your dog's size) can help relieve this. It is also a good idea to prevent your dog from licking and chewing the area as it can cause bacteria to enter under the skin. An Elizabethan collar or T-shirt can help with this.
If none of the above works or helps your dog to feel better, then having your vet take a look at the affected area is always a great idea.
