So we've been thinking that Carver is a pretty smart puppy. Not really afraid of things, easy to teach, takes a soft touch, etc...
After our walk, dinner and a few times outside, we just decided to relax in the front room and let him play with his toys. Next thing you know, he decides that he'd like to check out the upstairs! Keep in mind, it was a LONG time before Ansel dared to go upstairs and only managed it with the help of MMPB treats. We were so stunned, the camera was the last thing we thought of.
Carver thought it was fun, so he just kept going up and down long enough for me to chase down the camera and get a few pics of (in our minds) a milestone. I actually had to block off the stairs or he'd still be at it!
The good thing is that going up and down 12 steps will really tire a puppy out.
