At last year's Euromil in Folkestone (2015) Pegaso were selling a very nice, realistic bear that would work in that scale.
Only thing is, I'm not sure if it was a limited edition "show special" because it came in just a plain Pegaso box with no labelling or artwork, a quick look on their site just now drew a blank, and I didn't see it again at Euro this year - although on the other hand I wasn't particularly looking out for it this year, and it wasn't being touted as a "special" as far as I recall.
The bear is walking on all fours, has a suitably fierce expression with its mouth open in a roar, and comes in 3 parts (head/shoulders, right side torso & legs/left side torso & legs), all of which dry-fit together very nicely. It's white metal by the way, as you'd expect from Pegaso.
I picked one up at the show, and I'm not going to part with it because I have it in mind for something. But it might be worth dropping Pegaso an e-mail to ask if they still have any. Got to be worth a shot!
