Willie is the only Jack Russell I have known with such a pronounced retrieving instinct.
He will fetch a ball or a stuffed toy until you are tired of it.
I remember getting into a little bit of trouble when Willie was about six months old. He was wanting to play fetch really bad, and I ran him pretty hard through the mud.
Mostly white JRT’s don’t look so nice when they covered in mud.
You can tell from this beach photo that Willie will chase even a sand-covered tennis ball until the cows come home.
Now, if only I could find another golden retriever like that…
