Your not getting attacked because you don't compete or show, that would be silly.
Do you really believe that you are the only one posting that hasn't rescued some very serious cases? Dogs that were on deaths door or dogs so messed up mentally that it appeared the only option was to put them to sleep? But through knowledge, patience and lots of TLC that those dogs went on to wonderful forever homes and were no longer those poor pitiful rescues?
I agree, not all dogs are suited for competing, but that also extends to dogs that are not rescues as well.
Titles in many ways define a breeder/owner, but they are also owned by the dog, because those Titles are hard earned and should be respected, certainly not dismissed.
And I am very certain that our dogs, don't know nor care if they have a bunch of letters in front and behind their names, BUT most of them really enjoy the time spent with us earning all those letters. But having said that, it by no means that a dog that doesn't have any Titles is any less of a great dog to the person/s in their lives and that too also has to be respected.
