Is dog shampoo "no tears" shampoo, like baby shampoo?

When I bathe my dogs I try to avoid getting soap in their eyes, which means not washing their head or their ears as well as I’d like. However, I’m sure that over the years I’ve had to have leaked soap in their eyes at some point or another, but if so, it’s nothing they particularly reacted to, nothing beyond getting water in their eyes which they don’t really like.

So is the shampoo tears-free? If so, why doesn’t it state that on the shampoo bottle?
