That must be a once in a lifetime pic. JRT's are so full of energy. Great pics.
Actually, I have many pic's of Petie, along with my other dogs........lounging and sound asleep.
Petie, even with his high drives has always known how to use his off switch. When he was a little pup, we were on the sidelines watching Lure Coursing at a Terrier trial, he was the same as every dog there when watching, screaming and at the end of the leash wanting to chase. The second the lure stopped, he sat down and waited on a loose leash........calm, cool and collected. Until it started again lol.
