Ginna is now 10 pounds heavier than before she was bred.  We just received our Whelpwise equipment and I practiced listening to heartbeats last night.  She was a good girl and laid very still.  The first sound startled her at the first, but she was good with that cold gel on her tummy and me poking around.  It is fun to hear those heartbeats.  With the doppler, they sound sort of like the clippity clop of a horse running.
