I am uniquely qualified to answer, @Joan2055 , because I say yes and no.
I say yes to pets in my treehouse listing because they are a good fit there. I make sure my nightly rate covers my time cleaning up clouds of pet hair. Yes, everyone, even those without pets, have to pay it, but it's working for now.
I say no to pets in my bedroom listing because of extended family allergies and my husband's strong dislike of animals in houses. Guests do instant book and then write to tell me their perfectly-behaved, loved-by-everyone-who-sees-him dog will be coming, and I write back politely to ask them to cancel and book a pet-friendly listing. Not all of them call me names, but all of them cancel.
My advice is to follow your own rules. You set them up for a reason. If you say no pets, stick to it. If you say yes, build it into your price for now, and hope, like the rest of us, that someday a pet fee gets added to the booking process.
Just a note: There is a picture of a dog over the bed in your listing. You might want to swap that out for something that doesn't look so wonderfully pet-friendly if you do decide to stick to no pets. Some guests just look at the pictures...
