There are a few reasons I dont allow pets in my home
1- I have a small dog, and this is HER home. I don't want another animal coming in and her being territorial. Would be a bad experience all around.
2- My room is downstairs, and guests rooms are upstairs:
2a: If people are allergic to animals, there will not be pet hair in their room, my dog is only allowed on the lower floor of the house, and only sleeps on my bed, the living room couch, and her bed.
2b: If a dog is left unattended in a room upstairs, other guest rooms are up there and I dont want them to be bothered by the noise
3- Cats: I actually want to get a cat, but have decided not to because there are many more people with cat allergies than dog allergies. That mixed with the fact that I cannot really stop a cat from going into bedrooms, going up stairs, etc whereas dogs are easier to contain in their respective areas of the home.
That said- having a dog and traveling with her, it is SUPER appreciated when someone allows her to tag along, and also SUPER hard to find Airbnbs that will let her 🙂 Being a host myself is somewhat of an advantage when I ask other hosts, though, since we are on the same page in regards to how hard it is to keep your place clean and as allergy free as possible.
