There's a rearing bear with fearsome claws and teeth on the wall above the bar beside a huge halibut, and other bears elsewhere, one of them chasing a goldminer up a pillar.
There are mounted salmon and a dall sheep with curling horns, a bearskin rug, the heads of deer, moose and bison, assorted antlers, and the penile bone of a walrus - it's a house of horrors for Peta members.
It's loud, bustling and crowded, and the ambience is non-existent. What it is, though, is fun - and, surprisingly, fairly authentic.
That really is Wyatt Earp's gun, left behind in 1900 on his way to Nome. The building, moved several times, is "the oldest man-made attraction in Juneau". The bar was established in a tent on the beach in the early days of the 1880s gold rush.
Miners' tools and fishermen's paraphernalia hang on the bare-wood walls with other historical memorabilia and photos of the old days, when Ragtime Hattie played the piano in her white gloves and silver-dollar halter-neck top.
There are also more recent records: visitors are encouraged to add their names to the thousands already inscribed on walls, tables, chairs and bar stools.
The bar list offers liquor drinkers a choice of "Cheap Shit, Expensive Shit and Really Expensive Shit" as well as the Duck Farts, but beer is the wisest choice.
Alaskan Summer Ale, light and crisp, is popular but, even though it's pulled from a pump with an Orca handle, the Belgian-style Alaskan White, a wheat beer, is my favourite and slips down easily on a hot June day.
Waiters whisk past with trays of potato skins, reindeer sausage and burgers; local fish battered in a bun seems popular, and the pulled pork sandwich has a big fan at the next table.
The service is fast and bills are presented promptly, encouraging patrons to vacate their tables for the next customers, and to exit through the gift shop alongside. There, the usual caps and T-shirts are supplemented by more unusual knick-knacks such as braces ("suspenders" in American), red ribbon garters and personalised condoms.
Subtle and elegant it's not, but the Red Dog Saloon is a memorable must-visit for anyone passing through Juneau.
