For the past week my 12 year old, male German Shepherd hasn't been able to relax properly. He has been panting/breathing heavily (hot or cold weather), won't sit/lay down for longer than a few seconds until he gets straight back up and wonders around again. When he eventually does, he sleeps in different spots to where he usually does, wants to stay more closer to people. eg Now I leave my room open so he can come inside and sleep next to my bed and I today when I took a shower he was laying down outside the door when I got out.
At night he will come into my room and cry to me, I'm assuming, asking for attention which he then just wants to play with one of his toys. When I do play with him, he gets bored real quick and doesn't engage with me after a while. Then when I return to my room he repeats the same thing, it's as if he's just trying to get me out of my room. It's sort of like the behaviour when there's a thunderstorm.
Late at night or in the early hours of the morning, I can hear him wondering around the house. He never used to do this, he would usually sleep all through the night.
I've taken him to the vet and they claim he is "just getting old and developing brain dysfunctionalities - similar to Alzheimer's Disease in humans." The vet also claimed that he is in very good shape for his age, except for minor Arthritis in his hind legs.
I take him for short walks, as advised by the vet as to not aggrevate the Arthritis, ~15mins 3 or 4 times per week and he seems fine/acts normal but doesn't stop the puffing/panting afterwards.
I'm a little skeptical on the old age/Alzheimer's theory of the vet because he hasn't forgotten words or commands and knows all the usual spots like his food and water bowls. He just seems confused or worried.
I was wondering if anybody has had experience with this issue and if anybody could provide any tips or advice?
Thank you all for taking the time to read this.
