One thing I haven't read about (I'm sure it's here, I just haven't gone through all the archives yet) is puppies walking through or getting their poop on their paws. It's very important to wash or wipe (I use baby wipes) your puppies paws thoroughly when they are finished taking care of business. They will lick or chew their feet and nails and ingest their poo....that can make for one sick puppy. I forget what it's called, but I'm sure someone on here knows what the name of it is. Anyway...make sure you clean your puppies paws....his/her belly will thank you!!!!
