Any alternative to dog shampoo?

[permaquandry]

I've run out of dog shampoo and need to bath ddog, is there anything that I might find around the house OK to use as a one-off?

Baby shampoo?

Fairy liquid

Pantene round here! Makes him smell lovely!

I always use baby shampoo or if I've run out of it any shampoo I have in for dry hair, all my lot have long silky coats. They get human conditioner too.
