Absolutely true !!! There are MANY owner/handlers that successfully finish their dogs even as a puppy !!!! Actually - there are some that would not even consider handler due to bad experiences with those.
I think that if one shows her/his own dog actually has a better insight in what is going on in the ring.
It takes a lot of time and effort but rewards are great. I know a breeder who took her 4 month old and 5 year old kids to show , so she could show herself.
Politics are equally present in the UKC and AKC for any breed. Some breeders are also very hostile people and would try even to sabotage opposing dog

. As with everything else in life - show rig or grocery store - one can find fantastic human beings there as well as really crazy ones.
