Our puppies are enjoying solid food in addition to their time at Raven's milk bar. With the introduction of solid food brings a lot of solid mess. We have added a potty pen to the whelping box. The puppies have taken to it like fish take to water. It's so exciting to watch such young puppies wake up, climb into the adjoining pen, do their business, and return to their littermates. This litter is such a pleasure to raise. They are smart, sweet, and adorable. I couldn't be more pleased with them. I'm especially excited that they will be going to their new homes with a solid foundation in proper potty behaviors. New owners can thank me later.
