Can anyone recommend a really good whitening shampoo that's gets rid of wee stain?

Thanks

Cowboy Magic Shine In Yellow Out is very good at getting rid of wee stain.

I tried quite a few. Lightening and Whitening shampoos from All Systems are quite good, also White on White by Chris Christensen. I do like MD10 products a s well.
Recently I tried Kelco Plum White sold by Technogroom and my jaw dropped.
Best whitening shampoo ever in my opinion.

I also use all systems on 2 of my dogs and the chris christensen on another as his coat texture is slighlty different and so that seems to suit his coat better, so i think both are good shampoos!

Kelco Plum White is great :0)

Just had to say a big thank you!  :-)  I hesitated at the cost as it was an expensive delivery charge.

Oh WOW.  I have just used it on a white Chihuahua Long Coat bitch.  White is to die for! 

You are very welcome Jean.
That was exactly my reaction after first use and believe me I tried everything.
