I am going to buy a pug (only a couple weeks old) in a couple o' years. If he is lazy, I will train him from infancy to love excercising...and, I was wondering about another dog who would like to be on a cruise ship for a year, and travel to rainforests, the grand canyon, etc. It will just be me and my two dogs a pug and another dog (trying to get help for) on a marvelous journey around the world for two years! What dogs do you reccomend who can withstand heat, doesn't shed a lot, and loves the outdoors, companionship, and is a loving dog!
