More: Arko is an avid swimmer, hiker, tennis ball catcher and cuddler. He is the ultimate adventure dog, always ready to hop in the car and go for a hike. He has summited several Adirondack high peaks, swam in the Great Lakes and their tributaries. He often goes fly fishing with us and loves to run around on shore while we are in the water. He is the best companion that we could have ever asked for.
