How do I find pet-friendly hotels on Hotels.com?

I have a Maltipoo I travel with - she is 5 years old, well-trained, socialized, clean, and housebroken. I've never had any issues with her, and I'm quite confident I never will. She has already accompanied me more than a few times, and she loves traveling.

I've started looking for new traveling opportunities, and I came across this website. It looks pretty cool so far, but I can't quite figure out how to see which hotels are pet-friendly. Is there a pet-friendly filter on Hotels.com?
