You didn't think that only Misty pups were going to have a new area. I know they are young but I said why not.
How ere they with the change? They may have been stone cold shocked but no whimpering but they are sticking together. This is norm when they are this young. After the initial change they act as if nothing has changed but room and being able to look at other puppies.
Be sure to check out the videos.
It will take a bit of time for Dennis to put them on or to make sure all are on throughout the night but if this trio sticks together, mom will find all 3.
