The puppies have grown incredibly well in their first three weeks. The two bigger males are over 5 lbs, which is usually a weight that they hit somewhere around 4-5 weeks. These guys are just enormous. They're getting their voices too—squeaking, barking, and growling. It's a great time to start playing with them. Teeth are slowly coming in, so it won't be long before they're a bunch of curly toe-biting puppies.
