Thanks, your pup is gorgeous too. Actually my dogs are very quiet, I've only had 2 of them that were somewhat vocal, Hailey, and Mariya. Do you run Booga, we started sledding last year, I also have the springer bike attachment's on our mountain bikes, my DH takes Jonah on his, and I take the 2 girls on mine. I have an extension arm on both sides of my bike for them.
