Not just a brag, not just a stepping stone to a higher title, not just an adjunct to competitive scores, a title is a tribute to the dog that bears it, a way to honour the dog, an ultimate memorial.
It will remain in the record and in the memory for about as long as anything in the world can remain. And though the dog itself doesn't know or care that it's achievements have been noted, a title says many things in the world of humans where such things count.
A title says your dog was intelligent, adaptable, and good natured. It says your dog loved you enough to do the things that pleased you, however crazy they may have seemed.
In addition, a title says that you loved your dog, that you loved to spend time with your dog because it was a good dog, and that you believed in your dog enough to give it yet another chance when it failed, and in the end your faith was justified.
A title proves that your dog inspired you to that special relationship, enjoyed by so few, that in a world of disposable creatures, this dog with a title was greatly loved and loved greatly in return.
And when that dear, short life is over, the title remains as a memorial of the finest kind, the best you can give to a deserving friend.
Volumes of praise in one small set of initials before or after the name. A CH, obedience, agility etc. title is nothing less than true love and respect, given and recorded permanently.
