The pups are handling their Bio-Sensor exercises great, especially the new scents. Last night, they got to smell Bag Balm. Tonight it was pine tree. It's so funny watching them squirming around while you hold them, then freeze and sniff the scent that is under their nose. You can see the little brain cells firing, trying to figure out what changed. Considering that they are blind and deaf and smell is their main sense right now, it is fun to watch it develop. Of course, they also use that sense of smell to know that their momma has returned and brought their dinner with her too.
