would be nice if we had a sprayer

thats an american thing for sinks, we only have them in the shower. i tried the shower head on him the other day, didnt look very good hehe jks, but he just moaned when i turned it on, but im sure he will get used to it, we had our first bath in the bath and the second one in the sink, he didnt really like either and just started drinking the water, he might get a bit more used to it when he has had his second shot and can go and play with other dogs. also have read that using peoples shampoo on pups is bad for their skin, is this true or just urban myth, it says that it dries out their skin because it has a different PH level to doggy shampoo, even kids and baby shampoo is meant to be too much, any help on this one too?
