PeggySue,
some people don't get it. It's not important to them. I find that "nail mania" tends to be a show dog kinda thing. Most folks with dogs that don't show, don't do nails on a regular basis.

Heck, I keep grooming tools in the studio to brush out dogs that come in and haven't been groomed. I use leave-in conditioner to gloss up the coats of smooth-coated dogs. I put vasoline on noses to make them look black and glossy. But all of that comes from the experience of showing the dogs and knowing what to do before they go into the ring. Folks that don't do that, don't think of those things.

I wouldn't do anything special except maybe crop creatively so you don't see the nails (if possible). You won't win any points by lecturing. In the future, however, you might mention stuff like that to folks before they bring the dogs in.

As for training, I must admit that my own crew runs the gamut from Rowdy & Annie who will do anything I say and hold a pose until I release them to Sundance to whom the terms "sit" and "stay" are totally meaningless. And, yes, that's my fault not his. I doubt that you can sort out potential models based on whether or not they have their CGC:).
