Sasha is 12 now, soon to be 13. Our walks have changed muchly over the last few years. She will still lead, but we stop at every and anything that might have been visited by another dog. And we walk much more slowly than before. But she still wants to go for walks and I don't mind taking my little old lady for them and going at her pace. I will be very sad when she can't go or won't go for a walk any more.

Maybe try a walk with just Kia and go at her pace and let her stop and sniff the roses. She might just like that.
