They are actually totally housebroken. Kash had marked a few times in the foster home when he first got there. Then he was neutered, and either from that or just now knowing his new surroundings, he hasn't marked in weeks. They both cry at the door to go outside to pee.
I thought if they are that good at going outside, it might be best to keep them going outside, which is why we considered the doggy door. But, if they do come live with us, it might not be too hard to get them to pee on a pad while we're at work. Lucky for us, we can make Layla pee anywhere
If we get her to pee on a pad in the morning, and then put Kash and Izzy in an x-pen on our tile floor near the back door, with just their kennel and the already-peed-on pee pad, they might catch on to that's where they're supposed to go too. I'm not sure. Either way, accidents on the tile won't be too hard to clean up until they get the hang of it!
