were can we put an amount for people who likes to bring their dog

Hello, 

Thank you for reaching out! Right now, Booking does not have an option to list specific restrictions on pets. I would recommend listing your policy as 'Pets are allowed on request. Charges may apply'. 

If you would like more information from the guest, you can add a Message Template to be sent out when a guest makes a booking with your property. See instructions on how to do this below. 

Setting up Templates
