Chris and I climbed Wright Mountain in the Adirondacks last Monday (Chris' Birthday!) and it actually seemed more than do-able for Koda! The trail was packed down really well and it wasn't a very difficult winter trail. We climbed Wright in the summertime as well, and would also bring Koda then. However, 7 miles is still too long to risk him tiring out deep in the Adirondacks.
So! For now we are sticking to the city of Albany, do around 3 miles when we do our treks. I, myself, need better winter boots for the city, it's keeping me from staying out much longer.
As you can see, he is getting much bigger!! It really blows my mind. He leaves full-sized dog paw prints in the snow. He just had his 4 month birthday a few days ago... time flies!
