Looking for advice — extreme frustration with my dog

My dog is really important to me. Without going into much detail, he and I have been through a lot and I’m committed to making his life as good as possible. a couple of years ago we lived in San Francisco and we were happy. Then I moved to the East Coast, spent a year with my parents before starting a PhD. That was not the best experience, it was at the last stage of his adulthood before being elderly, and he got attacked by my mom‘s dog several times and we were in a shitty concrete hell suburbia that had no good places to walk him. I am very sympathetic to how difficult the transition has been.

Finally we have a place to ourselves again, and it sucks. I feel like he’s ruining my life. It’s been upsetting me to the point that I want to scream.

• he will not leave me alone. He needs to be where I am at all times. We live in a modest one bedroom apartment, and you can see every room from any other room. if I go into the bedroom and he’s in the living room, he has to hop off the couch and follow me 15 feet. If I go to the bathroom, he’s laying down outside the door. Because of his arthritis, I wish he would just stay and not walk unnecessarily.

• I take him on one good size walk and two or three small walks per day. these are the most frustrating times of my day. He lags behind me no matter how slowly I go. I have to keep the leash very short so that I don’t have him fearing off left and right. He wants to smell every single thing. He used to, be a good walker and he would stay at my side and come to that position if I signal him to. But in his old age, he just doesn’t listen to me, it’s not a matter of hearing. He completely ignores me.

• if he is not eating, out on a walk, or tearing up a stuffy, he is unhappy. He lays and will now and then sneezes or sighs.

• he has always had this problem where, a sudden loud noise will deeply disturb him. He will shake uncontrollably, and any attempt to soothe him, by talking to him or touching him, just makes him shake worse.

• he hounds me for food. The moment I touched something in the kitchen, he comes.

• I have gotten him several bowls to try slowing down his eating, but he eats like he’s starving. So I have to feed him in small bits, and if the bits are spread apart too far, he starts shaking like he’s being neglected. I have had him tested for diabetes or other issues, his blood work comes back normal.

• he always wants to sleep in my bed, but he does not want me to touch him. If we are sleeping back to back and our hips touch, he gets off the bed. And then he gets back on as soon as he sees a decent opportunity. we used to share the bed, because I have had a California king size bed by myself, and it was fine. But in the last year, it’s just like he hates it.

I have come to hate the sound of his collar jingling. I have nasty thoughts like waiting for the relief of him passing away. Sometime I have an aggressive voice, but I really do always try to keep my voice light and keep his tailwagging in my interactions with him. I’m sure he can sense my agitation though. It has become overwhelming. I don’t enjoy a single moment of our life together.

And I have to work and he needs to be walked several times a day and he will shake if he feels like he’s being neglected in that aspect, so when I have to go run errands, I take him with me, but I can never get anywhere because not only is he naturally slow. He has developed this instinct of lagging behind and he wants to stop and smell everything and it’s just annoying to have to constantly crouch down and Argue with him to get him to move his body. I don’t feel comfortable, forcing him to move, especially because of his arthritis.

Like I said, he used to have good training, but it has all fallen by the wayside and he is old and stubborn.

But this cannot continue. I Don’t believe either of us are happy. I would like some advice on how to effectively train him in the time that I have, I do not have the money to hire a trainer. I also ask that you handle your responses gently; I am extremely upset by this and I am aware of how shitty it sounds of me to speak of him so poorly, but my mental health is falling apart because of the lack of freedom and relaxation that I can find living with him.

I have no intention of rehoming him, and have always been committed to his safety, and comfort and mental and physical happiness. if I rehomed him, it would haunt me, it would devastate me. But I would do it if I believed he would be happier. But I don’t believe he would be, I have left him with my parents and other people in the past, and he just waits vigilantly for me to return.

Edit: I also want to say that I am open to advice on how I can manage myself and my feelings about this
