We have recently discovered, much to our chagrin, that our
3-year-old cocker spaniel, Hershey, is only housebroken at our house. He
has embarrassed us on three separate visits to the homes of friends and
relatives, two of which have no other animals living there. What's the
method of insuring that Hershey knows that going indoors is always wrong,
and not just at home? We've been careful to take him outside often. On one
visit, I took him out and he did his business very nicely, then came back
inside and did it again anyway, not 30 minutes later. He wasn't acting
anxious, and there has never been a dog living there whose "mark" he might
have reacted to. 30 minutes later, he did it again. Now we're reluctant to
take him indoors anywhere. Please help.
