It may just be me, but I think a four legged friend makes everything more fun.
Take my typical Sunday walk as an example. Insert Dog and suddenly everything becomes an adventure.
An excerpt from Dog's journal after our walk in Memory Grove: "Dear Diary, today I discovered snow. It is glorious. I can eat it, skid around in it, and the way it kicks up behind me when I run! Wow! I'm sure I must be dreaming, it can't possibly be true, but I think I can run faster in the snow. I will test this theory. One thing is sure, snow turns me into an invincible ninja.
