All the puppies seem to be thriving. They are eating well, as is Momma Lucky. We (our canine behaviorist and I) are doing some neurological training with them that I'll describe in more detail in the future, but has been shown to help puppies establish neural connections and helps them better cope with stress as adult dogs.
These guys are doing awesome, all are active, some already walking rather than belly scooting around. We couldn't be happier with their progress.
