One of my boys is starting to do that as well. He is already deaf. Im starting to think he is getting senile now too. He Comes in from outside lays down for a few minutes, gets up, wanders back to the door and stares outside like he hasn’t just been out. 

 Dealing with the hearing loss here as well. 
I just moved him to the couch & he’s like, perfect. Just where I want to be. Probably forgets he was even at the door. 

 It’s tough you want them to live as long as you do. 

 Longer. 

 Mine is 14, deaf and wobbly but he’s still loving his food and walks 

 As long as they’re happy, eating, drinking and walking all is great. 👍
