I've been fostering a 2 month old puppy for the past week, and since he can't go outside (waiting on the rest of his vaccinations!), I've had these spread around my apartment. They work great and completely absorb the mess he makes. Since we are in my small NYC apartment, though, I throw each pad away after he uses once since I don't want it just sitting there. When I foster in the future, I'll definitely be purchasing these again.
