Thanks for the advice.
He will walk, although it looks pained.He is not whining unless I cuddle him, then it is very slight (but he always talks when we cuddle...so maybe that's not too important...) His nose is wet, his gums are pink, his abdomen is soft and normal sized. I thought of bloat, too, but I don't think it's that because he has been doing this since yesterday afternoon, and what I know about bloat is that it is acute and fast.
I decided to still my mind a bit and medidated, with the intention that something, anything, come to me....a sign, an idea, a memory, an inclination, and what I saw was a scene from yesterday that I forgot about:
My younger, more spastic dog (same size) gets "crazy" when he knows there is another dog outside the yard, on the street, and when he can't "get to it" he goes after any nearby dog (usually the older, sometimes the younger). Usually just for a second, barks at him, tries to rile him up, etc. Many people told me they experience the same thing with 2 or more dogs.
But yesterday, the younger dog went totally nuts....I had to break it up, it was like a real dog fight (almost...no bites). It really only lasted for a few seconds, but it was intense. The older dog came over to me a whined and I comforted him and scolded the other and it was all forgotten (dogs are so present moment).
I was not sure what the memory meant, but started thinking he got just plain hurt in the scuffle, being old and all and remembering that he was droopy last night as well.
A friend who is very dog saavy stopped by to check in and she also didn't think it's GI related. He ran (a little strangely) to the door to greet her, so that was good, too. Then he laid down instantly again.
I was petting him and I inadvertantly pressed my elbow into his....and he let out a big YELP! Bingo. I think that the pain is muscle or skeletal now.
He also had no problem downing a little dog "cookie", just didn't want to get up to get it (yeah, I know, totally spoiled dog).
So I am concluding that he did indeed get injured yesterday and is doing what he feels he needs to, in order to rest it. He is a huge baby (thanks to me) anyway. And, in retrospect, every time he lies down, it is toward one side. He is not limping, so I don't think it's a paw, but higher up...elbow, shoulder, chest?....hmmmm.
The other very distinct possibility in the back of my mind is that he has several small tumors, mostly skin deep that I have checked regularly....and he may very well have more, internal ones, as he ages.I hope that is not the case, but I know it's possible.
I will take him in tomorrow and in the meantime, I will watch him like a hawk.
Thanks for caring....it means a lot to me....
