How do you prove my dog isn't nuisance barking?

To prove that your dog isn't nuisance barking, you can document the frequency and duration of the barking, noting the circumstances surrounding it (e.g., specific triggers like passing cars or other animals). Recording video evidence can also help demonstrate the context and intensity of the barking. Additionally, obtaining testimonials from neighbors or passersby who can attest to the dog's behavior can support your case. Finally, showing that you’ve taken training steps to manage any barking issues can further substantiate your claims.
