@irena:
Huge congrats although I have no idea what 4pt Major is
In the US for their championships, they need a total of 15 points, they only get points by going Winners Dog or Winners Bitch (can get addition points is they go Best of Breed or Best of Opp Sex). Points are based on the number of dogs/bitches in the classes. Different for different parts of the country. You can get 1 point, 2 points (called minor points), 3 points, 4 points and the highest is 5 points (3,4,5 are Major points).
They need at least two majors within the total of 15. Hardest to get are the majors as it depends on the number entered and usually when you have majors it is a bigger show with lots of good quality dogs entered.
Last year in Northern California we only had a total of about 6 shows that offered enough entry to get major points. And maybe about 10 shows in Southern California that offered enough of an entry to get major points. Traveling to Southern California for me is about a 6 to 8 hour drive.
