<human>:  How can I get my dog to stop barking at night?
<bot>: Start by having a routine that you and your dog can follow each night before bed. Give your dog plenty of exercise and mental stimulation throughout the day. If possible, have a designated spot in the house where your dog can sleep at night, and make sure it’s quiet, comfortable, and away from any noise. If your dog is barking at something outside, block the view with curtains or shades so that your dog cannot see it. Consider getting an automatic air or water sprays or sound devices to diffuse the barking. Positive reinforcement training can also help teach your dog when it is appropriate to bark and when it is not. Finally, if none of these strategies work, talk to your veterinarian about anti-anxiety medication or behavior modification techniques.
