Superness Shih Tzu litter is now a month old. They are already eating solid food. The puppies are now in the process of their potty training. In fact, puppy 2 already knows how to call us whenever he needs to pee or poo. There are several times in a day when we let them play outside their pen (but still inside our room). Puppy 2 is very amusing since he knows how to tell us that he wants to take some rest already. He will try to climb his pen and, if unsuccessful, will whine at us to put him inside his pen. This is why I think puppy 2 is very intelligent. At a very young age, he already knows how to communicate with us.
