I use DETANGLING SHAMPOO from
http://www.blessthebeasts.net/btb_online.html
This shampoo is great Chester does not have any matts since we started using it . It remove all the dirt from his paws and we only have to brush him once a week now because it really conditions. When we first used it on him I was like wowo.. oh my gosh... this is amazing . It leave him smelling great.
I don't mean to sound like a tv comercial but i really like this product.
Now they don't sell it at the stores in toronto anymore so we will have to order it online now.
