Okey-dokey, Ferrix, here are my comments for Donner Hund:
--His hit points should be 94, not 99 (10+10+(5x10)+24=94).
--You should add in the +2 bonus to Ride and Handle Animal skills check from the Hound Master PrC. Also, you gain a +2 synergy bonus to Ride from Handle Animal. I don't understand the +2 Circ notation under Ride though; is that from an item or something? I don't see anything in his gear that would account for it. Anyway, Donner's HA should be +22 (15 base + 2 Cha +3 feat + 2 PrC), and his Ride should also be +22 (15 base + 0 Dex + 3 feat + 2 synergy + 2 PrC).
--What is the Valorous property on his lance and which book is it from (from the price I assume it's a +1 special ability)? I don't think I've encountered that one.
--A few prices for items are a little off, though it ultimately doesn't impact much on his money. They are: +2 adamantine valorous lance (21,010 gp-- the mw quality is included in the price of the adamantine), +1 ghost touch longsword (8,315 gp-- you didn't include the mw and weapon price), mw silver kukri (328 gp-- 300 gp for mw, 20 gp for silver, 8 gp for the kukri), and 20 +1 arrows should cost 920 gp.
--Also, which book is saddlebags of providing in? I remember seeing it somewhere....
--Grizzle's +2 mithral chain shirt barding should be 5,200 gp, I think (4000 enhancement + 1000 mithral + 200 barding). Also,
magic fang potions cost 50 gp each so 4 of them should be 200 gp. Grizzle should then have an excess 1,600 gp to spend.
--As a 6th level Hound Master, Donner should have three pack members, not four.
--Also, the Fort saves for his pack members should be +8 (5 base + 3 Con), not +9.

Only thing I'm sort of questionable about is my cohort/mount, which I'm not entirely too certain I did things correctly on.
Okay, let's see. Grizzle is ECL 10. He's 6 HD, so that's 6 ECLs right there. If you slap the winged template on, that's another +2 LA. Since it also has the abilities of a paladin mount, that's another additional +2 LA on top (DMG, p. 200, first column, under "Paladin Cohort Mounts"). That brings us to ECL 10. If you want to keep those two fighter levels, you're going to have to drop the winged template (since you can't drop anything else). Also his HD would be 6d8+2d10+Con bonus (he doesn't get d10s for his dog levels)-- you would treat Grizzle as a multiclass dog/fighter when calculating BAB, saves, skills and whatnot.
I'm not sure how you did his stats (or how he managed to have a natural armor of +12!

)... my suggestion would be to start with a riding dog's base stats, add bonuses from the winged template on top if you're keeping that (+4 Dex, +2 Wis), plus any from the paladin special mount (+2 Str, and an Int of 7), plus 1 ability score gain for being 4 or more HD. You would not use the 28 point buy method to buy his stats (since all nonhumanoid cohorts simply use the base creature stats in the MM).
I also have a few other questions, such as how did Grizzle wind up with Improved Trip if he didn't take it as a feat (I know he would have Trip as a special ability for being a wardog)? Also, what is the Natural Heavyweight feat and where is it found?
I suppose if you like, I will stat out your dog for you to save you the hassle, if you tell me what you want.
