I'm looking for a dog sitter in my new town, and recently met up with a very nice person who has a couple of sweet dogs and a nice house. I like them, my dog likes them.

The only problem is that their dogs pee and poop in the house fairly often. I understand that some dogs, especially small dogs, can be really difficult to house train. But my dog is fully housetrained. He has never peed indoors and only pooped inside once when he was sick. I'm concerned that spending time with these dogs might mess up his training?

Have any of you been in a situation where a housetrained dog became less housetrained after hanging out with unhousetrained dogs?
