I agree that human shampoos and conditioners are not the right Ph for a dog. Most flaky skin is a food deficiency and/or not rinsing properly.
Coconut oil is helpful or some other Omega3 supplement. When you give him a bath just keep rinsing. If you are using a cup and not a spray to rinse it is very difficult to get the suds off the skin. Lift the hair up and rinse, rinse and rinse some more. |
