People want to slag on show dogs because they have big feels about dog shows, purebred dogs, whatever.
The one thing that show dogs have over most other dogs, especially pet dogs, is they know how to act in the tub, on the table, and they tolerate the touch of total strangers.
I still argue that every dog should be treated like a show dog.
Don't wait to train your dog to stand for bathing, grooming or physical examination.
Start early, stay til the job is done.
