Marlie is a happy dog, ready to walk, hike, run, and play. She wants to be with you, doing things. She would be a lot of fun to have as the only dog in the house. She does well on a leash, and loves her walks (and running would be even better!) She cannot be trusted around little dogs, and is aggressive toward other female dogs. She would be a great dog for the right, responsible dog owner. If you want an active companion, and you can give her what she needs, please consider her. She has a great personality, and her one ear down, one up is just adorable!
