Thank you for using Just Answer. My name is Rebecca; I am a veterinarian. Please give me a moment to type my answer.
I am sorry to hear you are concerned about Maximus. There could be many reasons why a dog his age does not want to walk any more. He may have arthritis (it would be unusual for an 8 year old German Shepherd not to have some arthritis), he may have a heart problem, he may have an internal illness, he could have DM(degenerative myelopathy, a neurologic condition seen in this breed).Is he eating normally? Any increase in thirst? Any weight loss? If you check his gums, by lifting his lips, are they pink in color or at all pale?
When a dog stops doing something they normally do, it is their way of telling us something is wrong, but it takes a physical exam by your veterinarian to start to figure out where the problem is.
How is Maximus doing? I have not heard back from you.Please let me know if this was helpful and if I can answer any other questions you may have.
