Thank you very much for the comprehensive responses.
Stella - I'm probably going to haunt the vet in the same way for awhile, and am going to be fairly insistant (tempered with appreciativeness) when it comes to getting baseline data where it's prudent to do so and ensuring he doesn't have any at risk systems that might collapse under one drug or another. I'm going to get multiple opinions too, since the course of treatment recommended by the vet down the road was pretty one dimensional and you could really sense the influence of Parnell in there, since no other company's products were available - no dietary supps or injectables made by others were represented. That being said, the vets there seem like good folks, knowledgeable, and very willing to take the time to answer questions.
~flower~ - That's the first I've heard to Adequan. I'll definitely be looking into that. With what Vet said, it sounds like it has been around a lot longer than the pentosan, and I definitely prefer to take a conservative approach and use a drug with a longer market history.
Sounds like I may be ODing the dog on fish oil a bit. He's about 40 lbs and gets approximately 10g a day. I use the liquid (no way this spoiled mutt would eat the pills) and swig from the same bottle myself. I have a digital kitchen scale that I used awhile back to get a sense of g/volume, and I just eyeball it when I pour it into his bowl (along with the supp powder and some milk so he'll eat it).
Thanks for the link to b-naturals. I'll be doing some reading there this evening. The current supp has no manganese or bromelain as far as I know (unless it's hidden in the other ingredients and I don't know it). I've added that to the 'vet question list' along with the yucca.
His diet is semi raw. I get 'pet mince' from the butcher, which is quite a high fat (by the feel of it) mix of bits 'n pieces. Then I grind up veggies (carrots, broccoli, celery, cauliflower) in the cuisinart, mix up a big batch at about 40% veg to 60% meat by volume, and freeze it in sandwich bags. I've been adding liver to the mix on and off too. He eats this 4-5 nights a week and gets "Advance" kibble the other few nights. It's not an ultra-expensive kibble (I've seen some that are more expensive than feeding him good cuts of steak! swear!), but it's pretty high quality... I guess. I got it at the vet, and the first ingredient listed is chicken and chicken meal, although the next 3 are rice, sorghum, and corn.

Fin won't swim more than a few strokes at the beach, even if I'm out there. I think the waves and undertow just freak him too much. As soon as the paws lose contact with the sand he heads straight for land again. He swims no problem in lakes and ponds tho, so after this post I'm taking him up to the park where there's a big pond. He loves swimming out after a ball, stick, whatever, and he's still convinced that he's going to be able to catch a duck one day. Sometimes you get to just sit back and watch him swim around and around after 'em. I'd never let him catch one, if there was a lame one out there or whatever, but it's just hilarious to watch. He really thinks he'll get there one day.

Vet - Yep, I'm definitely looking for a long term treatment other than NSAIDs. I'll ask the vet here about meloxicam though, since I predict he'll be getting a pill just occasionally if he overdoes it. His worst night was about a month ago (after a long walk on the beach with another dog), and he couldn't stand up at all. He was trying, and wound up dragging his back legs along the floor until I told him to stay and just picked him up wherever he needed to go for the night. It really hammered home how serious this was getting. Of course, 48 hours later you couldn't believe it was the same dog, jumping around and full of beans again, without any limping at all.
I had an xray done on him (he was really stoned afterwards and probably not too happy with me). The vet said it basically just confirmed that the problem was arthritis, but I'm glad we've got it for future reference. Of course, I didn't know how to interpret them, but the vet said his left hip and knee were the problem. She said that an ACL tear was a big concern and to avoid activities that require a quick change in direction. That's why I thought toys at the beach were a good idea (in the shallow surf), but I'm second guessing that now because maybe the 'bounding' required in shallow water (and on sand) is putting more stress on the joint than normal running.
He's not too overweight (although he has been in past years when I was living with my x) but the vet wanted him to lose about 3 or 4 lbs. He had a waistline but no real ribs basically. He's lost about 1.5 by now I'd say.
No sweat about the corticosteroids - there's no way in hell. I was thinking more of joint lubing stuff like deca or collagen synthesis promoting compounds like oxandrolone or gh, but Adequan and nutritional supps sound like a much better approach. I assume the MSM is 'Methylsulfonylmethane?' Massage, acupuncture, and ROM therapy are things I hadn't yet considered, so I'll ask each of the vets I see if they do it or have a rock solid recommendation they can give.
Just saw your second post re: yucca and saponins. I'll do my reading but will probably stick with low risk and proven treatments. My worst fear at the moment is giving him something that hurts or kills him. Back in '03 or '04 he had a 'hot spot' and the vet (a different one than present) gave him a cortisone shot which caused a near fatal flair up of pancreatitis. If they hadn't rehydrated him intraveniously he would have been dead within a day (that was on Christmas day of all days). So I'm glad they saved him, but I was ready to kill them when a vet there let it slip (props for honesty in hindsight, I guess) that it was the cortisone shot that caused the problem.

So I'm left with a sort of paranoia when it comes to 'lets give the dog this drug' situations.
Thanks again! We're off to the park!
