we have owned many "collie-crosses" as they were called from the 1950's to 1990's. Now I realize that some were OTSC's. :-)
I'm a retired teacher and in retirement I am a museum docent and artist. Our OTSC Ari is the first OTSC I've raised from puppyhood. He loves frisbee, and attends upon our cat or kisses her, when she lets him.
