It's hard not to spend a lot of time with these guys. The teeth are coming in, so you need to let them massage their gums by chewing on your ears, nose, fingers, toes, etc. They don't have the sharp teeth yet, so we've probably got another week or so before this really becomes more of a challenge.
In looking over our previous litters photos, these puppies are just huge. They're more like 4-5 week old puppies, and our previous litters have never been known for being undersized. Looking at Carmen's last litter (where birth weights were right around 16 ozs), these puppies look to be very similar to that litter's Day 28 photos. Hopefully they'll slow down soon, because no one really needs a 130 lb. Curly!
