My dogs are on CSJ Champ (4Border Collies and a Pug) in fact my pup now 6mths has been brought up on Champ(admittedly I do put other stuff in with it),Having 5 dogs I also like what comes out the other end quite dry and easy to pick up.It is less than £10 per bag Got no worries at all about it and they all lok very good on it.
I have tried easy peasy which is supposed to eliminate brown patches on the lawn. It hasnt worked for me but I know it has worked for some.
