I don't know much about titles across the pond. Here at home in North America, here is some title information.
Dogs of a English or European style are very popular and competitive in Canada it seems concentrated in Onterio. So, it is not uncommon for dogs of this type to be taken to Canada to compete and earn a Candian Championship.
For those in the West or Southwest that trip to Canada maybe cost prohibitive.
It is very difficult to successfully show a dog of this type to an AKC championship. So, it is less common to see.
There is the option to show in the UKC. In my area I have seen English/European style dogs compete and earn UKC Championships. They are not as hard to win as a AKC title but are still a great indicator the dog is a good representative of the breed. There are not as many of these shows and geographically they are not close to some areas.
There is also the International Dog shows. These are also not held as often and are not always available depending on your area. They award Championships a little differently. Every dog is judged and given a rating. 3 qualifying ratings = National Champion, 4 = International Champion. I love these shows as a place to practice and as a venue for rare or developing breeds. The downside for me is that it is not competition based. Meaning that dogs who have never even placed can be awarded Champion status. So, to me this title caries little weight if earned in a North America.
Finally, is the CCA a program brought to us by the GRCA. It is a valuable tool and personally to me I like it more than an International Championship.
I hope this information helps when trying to decipher pedigrees. Good luck!
