I found another tick on poor Sapphire.

It was about 2 weeks ago she had the last one. My question is, can they live in the house? She stays in the kitchen, so there's not really any place for them to stay, is there? There's no carpet in the kitchen. We wash her toys and her bed and her and there were none on any of those. She hasn't been outside since the last tick, either. We did have a party with some other dogs. Is it possible she got the tick from one of them? I just don't know what to do...
