He just loved tearing around the exercise yard, chasing balls, chasing me, happily running and jumping, barking at the other dogs passing by; he has typical terrier energy plus he is still very much a puppy. After about 20 minutes I realized Victor was not going to run out of energy any time soon, so we started our walk. Like any puppy he is thrilled with everything, fortunately he is small so his darting around on the leash is not really a problem. I think that once he has a home and matures this will solve itself.
Our second stop in the exercise yard was a little more fruitful. He happily comes when he is called because he is very affectionate and loves cuddles and pets. This crosses over making him reasonably promising at fetch. He loves running after the ball, and naturally wants to come when called - result - Fetch. He is such a sweet little guy, let's hope he finds his new family soon.
