The puppies ears opened this week and they are walking well. They still nurse and sleep a lot but they have started to interact with each other. There is a lot of mouthing behavior (no teeth yet) and cute puppy growls and yips. They usually wrestle briefly, fall over and then fall asleep. This week we have been introducing tactile items and new locations. Our family all spends time cuddling them (five people with five puppies works well). Now that they hear we are playing music and starting to intruduce novel sounds. Caper has started licking their faces and sometimes nurses in a sitting position or standing up. We are having a great time with the litter!
