Roxie is a big licker. Hubby just lets her lick all she wants. Drives me crazy after a bit. She will also lick something and then all of a sudden I'll notice her digging her teeth into it. She stops as soon as I tell her to so it's not a big problem. For some reason she loves to lick the registers. Can't figure this one out but it bugs the heck out of me. And isn't it funny for such little dogs how big of a tongue they have????
