He has a sry cough and he shakes and he is restless can't get comfortable and wanders around in circles and stares and falls alot
A dry cough in an older dog could suggest a respiratory condition such as chronic bronchitis or even congestive heart failure, especially if accompanied by difficulty breathing or reduced exercise tolerance. The shaking and restlessness may be due to discomfort or pain, which can be caused by a variety of conditions, including arthritis or other musculoskeletal issues common in senior dogs.
The circling, staring, and falling are particularly concerning as these could be signs of neurological issues. These symptoms could be related to cognitive dysfunction, which is similar to dementia in humans and more common in older dogs. Alternatively, they could indicate a more serious neurological condition such as a brain tumor or vestibular disease, which affects balance and coordination.
Please ensure that his living area is well-padded and free from obstacles that could cause harm if he stumbles. You may also want to provide a comfortable bed that's easy for him to get in and out of, and keep his food and water bowls within easy reach to minimize the need for movement that could lead to falls.
If your dog is experiencing any difficulty breathing, has a bluish tint to his gums or tongue, or collapses, these are emergencies, and he should be taken to a veterinary hospital immediately. Additionally, if he has prolonged episodes of disorientation, seizures, or any sudden worsening of his symptoms, these also warrant immediate veterinary attention.
I recommend that you take him to the hospital to determine the exact cause.
