Shampoo

Dogs’ skin and human skin have different Ph balances. Skin has a thin layer called the acid mantle, which protects the topmost layer of the skin from contaminants such as viruses and bacteria. It also keeps the body hydrated by absorbing water and reducing evaporation.

When we bathe, the acid mantle is washed away. To counter this, most soaps and shampoos have ingredients that moisturize and protect the skin until the acid mantle renews itself. In order for the acid mantle to do its job, the proper balance of acidity and alkalinity is crucial. This is called the Ph balance.

Human skin has a normal Ph balance of 5.5-5.6, which is on the acidic side. Dogs, on the other hand, have a normal Ph balance of 6.2-7.4, which is more neutral. Using a human shampoo on dogs disrupts the acid mantle, leaving your dog vulnerable to parasites, viruses, and bacteria. It also makes his skin feel dry and flaky, which can lead to repeated scratching and abrasions which makes it easy for bacteria to invade.
