I pretty much like them almost all as well. Don't care for breeds that have been bred to kill since that can creep up and surprise you way down the pedigree. Also could never ever, ever keep up with a Jack Russell.
I wonder if you were thinking of the Japanese Chin, they are very cat like, clean themselves, like to be up high on furniture and perfect for apartments because most are not vocal. I doubt they could be left alone for three days with only food and water though.....maybe with someone coming in a couple times a day taking them for walks. They do litter train easily and are small.
That one and the Papillon are nice. You are right you don't purchase a shih-tzu if you want to jog with your dog, or a St. Bernard if you want a lap dog
In other words like you said the dog you pick must work with your life style. So many people don't think of that. There is a book called 'Good Dog, Bad Dog' that is great and I don't remember the author at the moment. It tells the good and bad points of each breed and they all have them. lol
