No human soap is pet safe. No, Dial soap is not petting safe. You should try and never use these soap bars on your pets, such as vats and dogs. There is a scientific reason behind this statement.  You should not use these soap bars on your pets because the pH value of the skin of cats and dogs is significantly different from that of humans. So a bar soap designed to cater to humans cannot also cater to pets as effectively.  Instead of using human bar soaps, you can use bar soaps specially designed for pets. Such soaps are readily available in the market, and you can get your hands on them quickly.
