The short answer is, no, you can’t use human shampoo on dogs. Your dog may share your sofa, backyard, and living space, but there’s one thing you should never share with him: your shampoo. While human shampoo may keep your own hair silky and lustrous, most human shampoos include chemicals that are too harsh for your dog’s delicate skin.
The difference in pH Balance between humans and dogs
The pH levels of dog and human skin are vastly different. The acid mantle is a thin layer of skin that protects the stratum corneum, the highest layer of the skin, from pollutants like viruses and bacteria. Absorbing water and minimizing evaporation, helps keep the body hydrated. The acid layer is wiped away when we bathe. Most soaps and shampoos contain chemicals that hydrate and protect the skin as the acid mantle regenerates. The appropriate balance of acidity and alkalinity is essential for the acid mantle to function properly. This is referred to as the pH balance.
The pH balance of human skin is 5.5-5.6, which is somewhat acidic. Dogs, on the other hand, have a more neutral pH balance, ranging from 6.2 to 7.4. The acid mantle is disrupted when a human shampoo is used on a dog, leaving your dog exposed to parasites, viruses, and germs. It also causes their skin to become dry and flaky, leading to itching and abrasions. Bacteria can easily infiltrate as a result of this.
Who Has More Sensitive Skin?
The skin of dogs is significantly more delicate than ours. Canines have just 3-5 layers of skin cells, whereas we have 10-15 layers. Shampooing with an incorrect pH balance and/or strong chemicals can irritate a dog’s skin and strip away its protective oils.
As a result, without the acid mantle, dogs are vulnerable to a variety of unpleasant and even deadly problems, including dry flaky skin, rashes, itching, as well as infections.
Which Shampoo Should I Use On My Doggo?
While bathing your dog, it should go without saying that dog shampoo should always be your first pick. If you want the best for your dog, choose a shampoo designed exclusively for them. Dog shampoos are particularly formulated for your dog’s coat and skin, and with a wide range of alternatives to fit their breed and coat type, whether they require detangling shampoo or medicinal dog shampoo, they’re the ideal choice for your canine.
