This sounds like he is grouchy and restless due to pain. He is an older dog and probably has some arthritis causing discomfort. Also senior dogs can get senile just like elderly people. I recommend a veterinary exam. They can feel his joints to determine where he is painful and can prescribe medication for arthritis. If they think he has cognitive dysfunction there are supplements and medications to improve his brain function. Hills and purine both have dog foods for brain health also.
