I can sympathize, The older I get, the softer I become.
I get a little to attached to our livestock, cowdogs and barn cats.
I understand breeders are crossing corgies and border collies...they call them a cowboy corgie.
It hits home for me when I have got to put down an old , crippled rope horse.
I put on a million miles hauling , practicing and competing with a border collie in the seat beside me, as I go down the road. I miss them all. Take care...it hurts
