In order to see if there is something physical going on we went to the vet and did a huge blood draw to check his thyroid levels and a full panel. We also did a urine test. Waiting on results.
I really don't have a good enough grip on this to even say which direction I am looking but having made huge strides with his white dog issue we had a sudden and more intense return. It is so weird it is like a whole different dog takes over him for a few seconds and then he's back to himself. We are doing lots of behavioral stuff and talking to a trainer we have worked with in the past.
I also can't dismiss that strange sudden mild SA and about 10 days ago I woke up to a puddle on the floor. From a dog that was found as a stray at 12-14wks old and has NEVER had an accident and has been known to go nearly 24 hours without going if he just can't find 'the spot'. He had had a late night play with requisite huge drink but i had taken him out to pee about an hour or so afterward. Under no circumstances would it be normal for him not to make it overnight.
I have noticed he has some leg stiffness after he rests after a big play but not always, I first noticed this in June. I have never seen him limp or be reluctant to do anything.
He occasionally quivers after exercise.
Appetite is fine, weight is stable, goofiness intact.
At the vet I had him really check his knees and hips and he didn't find anything, said he might show a very slight elevation in his right hip and admitted that B would never show pain to him (or anyone).
Today he played with a buddy and then we walked our normal 3 miles. Never showed anything. He came in, laid down for a few minutes and when he got up he was limping. He was biting at his front leg while limping in the hind region.
I gave him an aspirin and he is crashed now.
So I don't have a clue folks. I was strongly leaning towards mild arthritis which with his activity levels and size would be unwelcome but understandable. But not sure now. I also thought that some of this stuff could be happening if the thyroid supplement is too high now. And the vet is back to being concerned about his kidney function. I'm wondering about additional auto-immune issues as he has a host of those already.
So not sure what to do next (other than wait for test results), keep working with the trainer who is as confused by this as we are and hope that we find some answers.
I appreciate any thoughts some of you may have
