LOL they are always full of surprises. I also live 20mins from work and traveled across a major bridge
for 8weeks back and forth on my lunch hr to take Buddy out. It was worth it because he was fully house trained at 5mos. I had to use two baby gates to keep him in the kitchen because he could jump one. Their bladder gets stronger as they get older. It is important to get them on a schedule. I have
to admit it though, it sure looks like he had lots of fun while you were at work.
