Does your dog have itchy skin? Letting them soak with an oatmeal/baking soda mix for several minutes just might do the trick. Most if your all of these ingredients are in your pantry.
Mix 1 part baking soda, 2 parts oatmeal, 2 parts water
(make sure your tub drain is fully plugged so the oatmeal doesn’t clog the drain)
Stand you dog in the tub and get their fur damp but not soaked with cool water. Take the oatmeal mix in handfuls and massage it into your dog’s coat and skin, avoiding their eyes. Allow the oatmeal mix to sit on your dog for at least five minutes, 15 if they will let you. Then, push off the excess slurry and rinse your pup with cool water. Gently pat them dry.
