@Lynn170 You have a lovely home listed and I wish you the best success. As for "pets allowed", there are many good reasons not to do that but if you want to, you must have clear rules about the pet or pets.
- Specify that prior permission must be obtained.
- Determine size and number of pets and if you allow cats, dogs, birds, etc.
- Have clear rules about whether the pet can be left alone in the house.
- Have a large enough security deposit to cover damage by the pet. Even well-behaved dogs will have "accidents" when subjected to travel.
- In addition to rules which guests might not stop to read, add under "what guests must know" the requirement to gain prior permission for pets. The guest must acknowledge reading this during the booking process.
As to how much you charge, do your own research for your area by looking at other homes that allow pets. You could also look at what local pet friendly hotels charge.
I am a dog and cat lover and have a dog in my home. I will not allow other animals in my home. Every owner thinks their dog or pet is an angel. If you allow pets then people with pet allergies will not book your space. Look at the many discussion threads on this topic as a good source of education.
