Chris Littleton, Colorado 3/11/2014 4:52:09 PM We have 2 female leonberger's,or Leo's as they're called. They are the gentlest of dogs,great with kids very tuned in to one's mood. Very easy to train,but can be willful. They are the best of the big dogs. And absolutely beautiful. But do need daily brushing,they love the snow and cold weather.A non aggressive dog.
