@Jason1638 It's been a long time since I updated my listing, as I've been closed to bookings since March 2020 due to Covid and having a home-share, so am not aware of any changes.
But I put it in "Other things to note". I also said "Please do not book this listing if you have pet allergies or are afraid of dogs".
It would be a good idea to include a photo of your pets in the photo gallery as well, captioned "My co-hosts".
