Yes the first place to start is at the shows, we watched ringside for about 5 years before we ever stepped foot into the ring ourselves. We learned so much by just watching and talking with breeder/owner/handlers.
It is very expensive, we spend thousands every year on entry fees alone, not to mention travel, hotels, grooming supplies, show supplies (seems there is always something else to buy), clothes for showing...etc...it does get pricey but so do many hobbies and sports. This is pretty much what I spend my fun money on...but I so enjoy it.
We are showing this weekend...going to be in the 90's and humid...so I just spent $50 on fans and the batteries for them for the yorkies. Gotta keep them cool. Then they have their cooling beds too.
Gotta spoil them where ever you go.
