I always tell people, that shelties become little snapping turtles/alligators/sharks w/ treats. I have to remember to get the treat down at or below their nose level, try to keep them in a sit, and use a "niiiiiiiicccccccce" or "gentle" command, when giving a treat. The at/below nose level is hard when you are in a wheelchair, your arm is only 12" long and your beloved breed tends to be at the 16" height (and shorter when a puppy).
Fortunately, no blood draws for about a couple of weeks.
