NEW YORK (AP) — Traveling with dogs can be stressful. Throw in holiday home stays at one of the most chaotic times of the year and double that stress for humans and animals alike — especially when hosts have pets of their own.

Large gatherings, unfamiliar smells and sounds, mixing older or sedate dogs with energetic pups, and introducing small children or cats to a dog with no prior exposure are among the issues that can spoil the experience or, worst case, cause physical harm.
