The puppies are now officially 3 weeks old and starting to resemble dogs. Their Chihuahua features will begin to appear over the next couple weeks. But until then, they are all exploring their new abilities and it is fun to watch.
In addition to seeing and hearing, they are working on their walking skills and have started to sit up more and more. I suspect they will be crawling over the walls of the whelping box very soon. It’s usually the four-week mark that requires the puppy playpen set up. I best get the stuff out and ready aye?
