They need a diaper for about 4 days. After that, I just wash the couvh cover every couple of days. And they dont sleep on my bed for about a week. I bought them female dog panties that I fashioned a type of harness to keep them from pulling them off. The diaper hoes on first, the the panties with the harness. They only need to go outside 3 times a day, so it is not too much trouble.
