Don't ever use human shampoos on your dog. Using your shampoo for your dog might seem sensible, but their pH levels are completely different.
Washing your dog with your shampoo may cause their skin to become dry and irritated. Human shampoos, even baby shampoos, are highly irritating to a dog's sensitive skin.
If you have a puppy, wash it gently with puppy shampoo, not baby shampoo. The formula is even milder and will bring out the best in your puppy without ever irritating the skin.
There are shampoo formulas for every type of dog, and they will help bring out the healthy luster and texture in your dog's fur that you love to see.
