There's also been some research on the PH levels among breeds and the GSD has the highest known PH among dogs. They are also known for skin issues, likely due to incorrect shampoos. In all cases, human and dog, a shampoo that is sls and als free is a better choice as both these ingredients are known irritants.

What's sls and als?
