Shampoo - Alkaline vs Acidic

I'm looking for some of you who majored in Chemistry during College.

"The first rule of dog bathing is not to use a human shampoo. The pH of dog skin is very different to that of human skin. While our skin has a pH of around 5.5 to 5.6, your dog's skin is much more neutral, averaging a pH of between 6.2 and 7.4. Shampoos formulated for humans are much more acidic than those for dogs, and using a human shampoo can upset the balance of a dog's skin." Source:

If a dog shampoo is too acidic, it would have a drying effect on my dogs' skin and *probably* make her itchy, wouldn't you think?

To reverse that, what if you had a shampoo that's too alkaline? What *likely* effect would it have on my dogs' skin?

Thank you!

Well if you go toooo alkaline you will burn the skin. Not that it matters but I actually do have a degree in chemistry and think a dog groomer would give the best answer .

FWIW I use everyday Shea body wash on my skin and hair - definitely a bit alkaline and may just use that on the dogs. My scalp has been much healthier than with "pH balanced" shampoos . I have been known to wash my dogs with Dr Bronner or with Dawn both of which a little harsh for me.
