Why is my 15-year-old dog barking at nothing outside at night?

Pet's info: Dog | Yorkipoo | Male | neutered | 14 years and 1 month old | 10 lbs

Why is my dog barking incessantly at night! He is a Male yorkie poo. He is 15 years old and is otherwise in good health. But, as it gets dark outside, he barks at the glass sliding door like he sees something, but nothing is there. Any ideas?

At his age, it could be a degree of canine cognitive dysfunction (senility). You would need to have Chewy examined by your veterinarian for confirmation. If this is the case, there are medications and other treatment options. https://www.petcoach.co/article/aging-gracefully-6-things-to-know-about-canine-cognitive-dysfunct/ https://www.petcoach.co/article/4-signs-of-cognitive-dysfunction-in-dogs/
