Hi Liz,
A dog needs to win 3 CCs (Challenge Certificates) under 3 different judges, to gain the title of Champion. The different breeds have varying numbers of pairs of CCs (one for Best Dog in Breed, and one for Best Bitch in Breed) allocated by the Kennel Club, and these are only awarded at Championship Shows.
A Stud Book number is given when a dog has won at a certain level, and means that it has lifetime qualification to Crufts, as does Champion status.
Puppy awards can count towards a Junior Warrant, but that's different again (and keeps changing, so I've lost track of what's needed)!
Hope this helps a little.
:)
