Gemma wears a snood before she eats. When she was being shown she would wear a lycra coat to keep her coat straight the night before the show. She regularly has her feet hair trimmed so yes you could paint her nails, not that you would be able to see it but it wouldn't stress her.
If she sees her old lycra coat she gets excited because she always loved being shown. She reacts to it the same way she does if she sees her collar and lead.
One whippet likes a coat, she has been brought up wearing it.
As for not letting a dog watch sex on TV - yep the person is slightly weird.
This person is obviously a bit (lot) extreme, but they are loved and that's probably preferable to how some dogs gets treated.
