Here are the basic dog shows titles. In fact, there are more but just to give you an idea it is quite enough. They are listed from the most to the "least" valuable.
 
1. BOB
2. CACIB
3. res.CACIB
4. CAC, CAJC, CWC, CACa
5. res.CAC, res.CAJC
 
All titles here are explained in detail in Vocabulary and Dog Shows where you can also find out where you can win them. I only have to say I've got them all:)
