This one is so identical to my dog, I thought someone had borrowed a photo and used it on their site. He was so nervous when we first got him, we literally had to carry him out of the door and slowly coax him down to the nearby park.
He now runs off the lead with his adopted pack of six dogs, mainly retrievers. He loves every minute of their company and doesn't stop running when with them.
It's very satisfying to find him sparko asleep five minutes after getting home.
