Amen to that. Guaranteeing anything like that is setting yourself up for a refund demand.

You can and should note that your animals will be on the property and that people who are afraid of dogs or cats should not book.
You have every right to ban pets but, as we are currently discussing on another thread, you cannot refuse to accept service or emotional support animals nor can you demand documentation.
And people will lie.
A fair deterrent might be to say that your dog(s) are territorial and will not tolerate strange dogs or cats on the property.
