>>1562161My girl is a rottie mix too. I got her DNA tested, and she is a clean 50% rottie, and the rest is mostly chow chow and cocker spaniel. She's a couch potato, though, and not much of a hiker. She gets a 1 mile walk every day and after that she's ready to chill on the couch and maybe play with her toys inside later. She gets overheated easily, especially in the summer months since it's extremely humid where I live and gets up to 110 degrees.
