Hotels for Pet Allergies: What "Pet-Friendly" Doesn't Tell You

Because "pet-friendly" isn't always friendly.

If you're allergic to dogs or cats, a "pet-friendly" hotel isn't just a preference to avoid — it can mean a room that's actually had an animal in it. Pet dander and residue can linger in carpets, upholstery, and bedding well after a standard clean, and hotels generally don't tell you which specific rooms have ever housed a pet versus which haven't. Booking a hotel that simply doesn't allow pets at all sidesteps the question entirely.

The problem is that hotel booking sites are built to help you find pet-friendly rooms, not avoid them — there's a filter for "allows pets," but never one for "doesn't." That means checking each listing's own House Rules or policy text by hand, one at a time.

How GoNoGo helps

GoNoGo is a free browser extension for Chrome and Edge that reads a hotel listing's own published pet policy and shows you immediately whether pets are allowed, not allowed, or not specified — on Booking.com, Expedia, Hotels.com, Agoda, TripAdvisor, Priceline, and Trip.com. On search-results pages, it flags listings it can confirm are pet-friendly and lets you hide exactly those, so you're browsing a shorter, more relevant list rather than opening every result to check by hand.

What "not specified" means

Sometimes a listing genuinely doesn't mention pets either way. GoNoGo shows this plainly as "Pet Policy Not Specified" rather than guessing — it's the honest answer, not a failure. If avoiding pet exposure is critical for your trip, that's worth a direct message to the property before booking.

Service animals
In many regions, service animals are legally exempt from standard pet policies. GoNoGo does not attempt to classify or exclude these cases — it simply reflects the general pet policy stated in the listing, presenting the same information in a more accessible way.
