Nanook is my almost 14 year old shep mix.
He has some major health probblems. I rescued him from the shelter 13 years ago, he was 8 months.
Something happened to him before I got him that I did not find out until a few years ago, he was shot by bird shot & the whole left side of him is covered with them. He has bad arthritis due to that.
He is starting to become hard of hearing & has very very slight cataracts. He also has a very large tumor growing under & over his rib cage making nearly impossible to operate on especially at his age.
He has always been scared of loud noises but it is getting worse.
He seems to be more clingy, especially on days where his arthritis is not too bad.
He is more spoiled so between that & the hard of hearing he does not listen as good as he used to but he is still pretty darn obedient. But he has always been very obedient so it really isn't that different as before I would ask him things instead fo telling him, just I have been giving him more slack lately.
He can not manuver as good as he used to therefore he trips a bit more & also can not groom himself as well as he used to.

On his good days though he acts like a puppy, he still looks very young. His teeth are in better shape than my other dogs.

He did snap & actually broke my skin a few weeks ago. I posted here about it. We have no idea what caused it, none what so ever. Maybe he was snapping at a bug & got me, maybe he was scared, maybe it was medical, like he was in a trance or something not sure but even then he did not act viscious nor did he growl or bark or anything. Other than that one occasion he has never ever been snappy or anything. I doubt he would even hurt a flea.

Other than that, mainly medical issues he has not changed too awful much. And it has been very gradual too.

He is my buddy!
