Good point Hussler about the 50kg plus but the horse does need the jockey (plus saddle and related gear) to get it going and steer it. For most quality dogs, an old rag on a long piece of string would be sufficient. The good ones will chase anything that moves. And by the way, my misses just made herself a cup of coffee but didn't ask me if I wanted one. Wouldn't happen in Coop's household.
