Championship shows are more formal and you can qualify for Crufts:
As we have stud book band E dogs to qualify you need to get a 1st, 2nd, or 3rd at a championship show in certain classes, of which Junior is one. as LKA is late if you placed in your class you will have time to get your entry into Crufts too.
The other thing is this is how you get a ShCh prefix, to do this you need to get Best of Breed, Best of Sex, earn yourself a .challenge certificate (CC) three of these and you have got yourself a show champion. I haven't got one yet but you need to have a goal don't you!!
For you it is the crufts qualification you would be after. There are other aspects to Ch shows like stud book numbers but these don't come until the dogs get a bit older really.
Both are good fun, the Ch shows are more for the adrenaline junkie IMO!!
