My heart breaks a little at a time

Mr. T now wants to be carried for some of our daily walk. For 14 years we have walked three miles a day in every kind of weather condition from 30 below on the tundra outside of Barrow to 80 above on a hot summer day in Anchorage.  He always liked the cold best.  Now, as spring is arriving and the snow is melting, his back legs seem to be getting weaker. He can make most of the walk but towards the end, if I pick him up for the uphill part of the journey, he doesn’t fight or get antsy or wiggle to get down.  He just sits in my arms and is content to watch the world go by.  Long goodbyes are truly the hardest.
