Sorry for your loss GB. Ruby sounds like she was a real character.
I have a 13 year old German shorthaired pointer myself, a very similar dog to the Vizsla. The Vizsla also known as the Hungarian pointer.
I remember over 10 years ago they just suddenly appeared and before long they were everywhere, which shows what a good dog they are. I love their eyes.
I get what you mean about cat-like, my pointer Ben can contort himself into crazy positions and cleans himself like a cat.
She obviously had a good and happy life and that's all you can give them.
Take comfort from the time you had together.
