My senior dog is anxious. Could it be dementia or hearing loss?

Pet's info: Dog | Yorkshire Terrier | Female | spayed | 30 lbs
My 13 yr old Yorkshire terrier has recently ( last 3 days) been showing signs of anxiety similarly to the way she reacts to the smoke alarm going off, but there are no signs that I can hear. I was wondering if this could be due to hearing lose or do you think there is something else going on?

You are correct there could be something else going on. In senior dogs like Molly, they can develop a condition called canine cognitive dysfunction. This is similar to dementia in humans, and it would cause her to behavior strangely at times. I would have Molly seen by a vet. The vet can diagnose if she does have cognitive canine dysfunction by doing a physical exam, blood tests, urinalysis, and x-rays to rule out any health problems that could potentially cause her symptoms. If canine cognitive dysfunction is diagnosed, the vet can discuss treatment with you. While it cannot be cured, it can be managed with mediations, behavioral therapy, and special diets.

Yes these are early signs of dementia (cognitive dysfunction), along with staring at the walls, altered mentation, forgetting familiar faces, and aimless wandering. There is a medication that can help reduce symptoms associated with this disorder called Selegeline that you can inquire about through your veterinarian. There is also a Rx brand good called Hills B/D that is designed to help pets manage brain related changes and provide antioxidants to support brain health.

Thank you for submitting your question regarding Miko! Given his age, he may be experiencing something known as canine cognitive dysfunction. This is somewhat similar to Alzheimer's disease in people. It is characterized by becoming stuck in corners or small rooms, pacing, panting, and vocalizing at night. Some dogs will become withdrawn and show appetite changes. Other will seem to forget their house training. It would be worthwhile to have him evaluated by his veterinarian to determine if this is possibly the cause of his signs or if he is experiencing something else. I hope this information helps!
