Oatmeal, with its many lipids, proteins and protective chemical compounds known as saponins, has long been used as a soothing treatment for numerous itchy skin conditions ranging from dry skin and bug bites to eczema and psoriasis. Though humans are the ones we normally think of as taking oatmeal baths, dogs can also benefit from the positive effects of oatmeal. Homemade oatmeal soap can be used as an alternative to often harsh commercial pet shampoos, or to help alleviate symptoms of allergies, flea and tick bites or other itchy skin conditions.
Grind 1 cup of plain oatmeal in a blender or food processor until it becomes a consistent powder.
Pour the ground oatmeal into a mixing bowl with 1 cup baking soda and 1 quart warm (but not hot) water.
Mix the ingredients thoroughly until they form a wet paste.
Apply the oatmeal soap directly to your dog's saturated coat, allow it to sit for five minutes and then rinse completely.
