An aging pet

After 10 good years of being with us, our border-collie/lab is starting to show some serious signs of aging.  Her back leg is very arthritic, and she spends a good deal of time crying, but our vet has given us some good meds for her, so we're hoping we'll be able to keep her for a while longer.  Yesterday we had a little photoshoot, just the two of us.  She's such a beautiful dog!
