Why so happy Spence? I think it's because he jumped on the couch and rolled over and asked Cassie for a belly rub! He's also been working hard on learning "sit" and is getting pretty good at it too!
We've just started on teaching him some "nosework" (nose work encourages your dog's natural drive to hunt, coupled with their special talent for picking up scents and finding their source) with boxes out in the garage... He sure is having fun finding treats in boxes!
