They have outgrown their cardboard box. I put them in a kiddie wading pool. This was fine for overnight, But this morning little mommiedog began to fuss, and tried to move the puppies under the couch.
Translation: She wants them in a den now. Their eyes will begin to open in a day or two, and they need to be in a darkened environment.
They are now in a covered kennel-crate, and all is well.
The wading pool is standing by for when they start coming out of the den and learning to walk.
