I'm sure he is in some pain, thing is, it's impossible to tell just how much as he is incredibly stoic, more than other dogs I've had. Meds are not an option for reasons I won't go into here.Art, If the old dog is not in pain, or sick, let it hang around for awhile. Give it a dose of CBD or CBC.
He's not sick, that I know of(no vetting here-long story), is eating drinking peeing and pooping ok. Tho on occasion he drops a turd in the house and has a hard time squatting to eliminate. His back legs have been wonky for a couple years, pinched nerves from back injury IMO, and he did go thru a bout of anaplasmosis around the same time. The back legs thing has greatly reducing his dexterity in many situations. He will not walk on hard floors, too slippery and can end up splay-legged and 'stuck'....took me weeks to determine why he wouldn't go into bathroom where his water was kept. I now have rubber backed throw rugs in many places. He can't get up on the bed or even the couch anymore. He has trouble doing the circling and getting his back legs into position before laying down anywhere, getting back up is just as arduous.
Our main egress in and out of the house includes a full set of stairs(walkout ranch), I have to go down the stairs on my butt in front of him and coax him down a step at time and hope I can catch him if he falls. He can't ride in the van anymore, too unstable standing and can't really 'sit' any more. Two front steps off the deck to dog yard for morning pee are OK, but I had to install a light over steps.
He still prompts to play but rarely and gives up pretty quick. He still likes to wander the fields and yards and even runs a bit....but again not for long. I think that's a sign of pain.
He fell a couple times last winter on the slick front steps and back patio, my own mobility issues made that a scary situation, I almost went down trying to get him back up onto his feet. I can just pick him up, and if he fights it...SMH. He's a 12-13yo standard poodle, 24" at the shoulder and 45lbs. I am isolated here with no 'help', unless it's a dire emergency.
Phew, that got long, sorry, guess I needed to 'vent'...thanks for 'listening'.
Anyway, I can't see him going thru another winter, so not tomorrow but before the ground freezes.
