Well – with Sassy’s puppies coming, they really need more room than Martini’s pups. The puppy playpen is designed for active pups and their training needs. We have a portable playpen for pups too so I switched them all to it for a cozier place to chill. It actually works perfectly. They have room to romp with plenty of room to nap. Martini has enough room too for feedings. Of course at the rate they are growing, they will be in the puppy playpen soon enough.
