I have a Yellow Lab named Daisy who was a puppy until she was 4 years old. I've had several dogs but she's the best I've ever owned - quite a personality and demanding, but she will sell her soul to play with a Frisbee and she loves the kids.
Your pup will be fine!
Get out and ride - the commute this morning was soaking wet due to humidity in KC. I just slowed down and took it easy. It was still much nicer than driving the internal combustion contraption.
