Each show a dog is in he may get a ribbon and be able to earn points. When they get enough points they become a champion of whatever they are doing weight pull, conformation, back in the day when it was legal fights wins got points as well. When the dog gets even more its can become Gr. Ch which is Grand Champion. There are soooo many I will try and find a list someone made and post it lol. Lots of events so it depends on the dog to what it means. So many initials . I don't know then off hand I always have to look them up.
