As someone who rents with dogs, I am grateful to be able to rent at all. If the person does not want to spay her dog to rent the property, fine and understandable, but then she is free to locate another rental property. Just as I did when I applied to rent somewhere and discovered they wanted any dogs on the property to live outside. There are all sorts of rules at various rental properties when you want to have pets..breed restrictions, no cats, no large dogs, etc...pet owning renters just have to find one that suits them
