Hi! Hello! How the h*ck are ya?    Get out your science books out because we're talking dog science this week. We've got Julie Dixon Jackson (host of Cut off Genes) to teach us all about dog DNA and tell us about her own dogs! We hear all about Duggy the greyhound in our first international My Mutt Minute. Plus, Allegra tells us all about the two GIANT dogs she sat this week.    Grab a Great Dane and tune in!
