But, OP is in Canada, so process of finishing a champion is just slightly different than previously described in this thread. Back when I lived in Upstate NY in the 1970s, I finished three or four Irish Wolfhounds in Canada. Back then, they only needed 10 points to finish (as opposed to 15 points in the US), and needed no majors! Now dogs need at least one major to finish in Canada.
I recall I thought the atmosphere at the Canadian shows was very friendly and relaxed, compared to shows in the US. I don’t know if that is still the case, I only occasionally attend Specialty shows in Canada, I haven’t been to an all-breed show in Canada in many years.
OP, I am so glad to hear you enjoyed spectating at an all-breed show! Entries at all-breed AKC shows have been declining in the past few years, we are always trying to figure out how to increase entries, as well as attract new people to the sport.
