What would you all recommend about taking a dog up to the top of Mt Washington? I've seen many dogs hiking with their owners but I'm not sure if my dog would make it. He's in good shape and is outside for exercise. The only concern I have is that he is going to be nine years old this October. He shows very little signs of aging and is extremely healthy. Also. What's the rule about dogs and the summit? Are they allowed in the building or only outside?

Here's a couple recent pictures of Charlie if it helps.
