My brother Team Chases his ex-racer (called Costa, was called Cosmic Ranger while racing).
As for horse poo, there is pretty much nothing you can catch from horses full stop, let alone their poo. Dogs poo (and dogs in general) carry tons of diseases, and are far more dangerous for your health (hence why doggy dodoos have to be picked up, and the GG's gon't) back in the olden days, poor people used to live in with their horses for warmth, but the dogs never lived inside, the diseases were the reasons why (or so my Dad tells me!)
