So, in the interest of research, I can attest to an actual problem with dogs and chicken bones. My dog, we’ll call him Tiberius, was acting funny. He’d been out earlier on a walk off lead in a rural but not desolate area, in a part of Canada well known for it’s love of chicken, and not known for environmentalism. The next day he wasn’t eating properly. He’s a scrawny standard poodle who loves his food, so I checked it out. He’d chomped down on a chicken bone - probably a drumstick, as I recall - and it had wedged in his upper palate, neatly stuck in from the back teeth on one side to the back teeth on the other. Dogs, of course, have no fingers and can’t get peanut butter off the roof of their mouths, much less chicken. It took a bit of force, but I was able to yoink it out, and he was fine.
My dog was a street dog. Hence, has eaten his share of every kind of bone. And he loves them.
He was three years old when he adopted me. I try to keep him from eating bones. If there is a chicken leg, I hold on to the bone and he breaks off the nubbin. Then I turn it around and he eats the other nubbin. He breaks them down before swallowing. And I throw away the center part.
I give him raw beef bones and he chews on them for days.
The problem being is that dogs don’t have molars.
No other dogs present. The gopher was just sitting out on the lawn for some reason. My mother called Sparky, thinking he would play with it or something. He bounded up, took one look, and swallowed the poor thing whole. No bad consequences that I remember.
So, I think the end result here is- *be careful *giving chicken bones to your dog. Smaller softer bones might be Ok (for larger more robust breeds), but larger, brittle bones can be bad.
Don’t freak out if your dog accidentally gets into some, however.
My bird dogs which are a fairly large breed got all the table scraps including chicken bones and turkey carcasses. In 20 years I never had a problem, maybe I was just lucky. I don’t give my chihuahua chicken bones.
Well, maybe some for the gopher.
My friends have a smallish pit bull mix, full parentage unknown. Friendliest dog evah.
I set down a pair of leather/polyester webbing work gloves; came back later to find only a small piece of chewed polyester webbing. Oh no, he didn’t, did he? But he seemed okay, full of his usual energy, so… sigh.
It most all came out in the end, as these things do. But I’ll be more careful in the future, I tell ya.
This finally explains what the main joke is in the Far Side cartoon where the anthropomorphic dog sees the sandwich his wife serves him only has a single bone and thinks “Another chicken leg bone…I think she’s trying to kill me”. Without me knowing that it was an established part of lore that you shouldn’t give dogs chicken leg bones, it didn’t really connect with me at all and I always felt there was something to the joke that I was missing.
My dog crushes bones to rubble and eats them. She’s even eaten a kong. We’ve never given her poultry bones before, but my husband argues her case that she should get a turkey bone on Thanksgiving. He argues that life is about quality not quantity, and one of our dog’s greatest joys in life is food, especially variety. So if there’s a minuscule chance that she could be hurt by a splinter, he argues it’d be worth it for the chance to enjoy a big juicy turkey bone. We had similar arguments on whether or not to let the cats outside.

ETA our dog has also eaten crockery & glasses & somehow wasn’t damaged by the sharp edges. 
In college, a good friend lived next door to a BBQ shack. They had a couple of yard dogs that subsisted entirely on leftover cooked chicken and ribs. Seemed as healthy (and mean) as could be!
Saw the same guy’s dog - a lab mix, inhale a rabbit whole.
I recall one day I took my 2 goldens to a dog park. Apparently several rabbits had denned there overnight. (Talk about culling the herd! They couldn’t find ANYWHERE else to reproduce?) Both dogs came trotting to me w/ baby rabbits in their mouths. When I told them to “Drop!”, you could almost see them consider it a minute before swallowing them whole as fast as they could. They each must’ve inhaled 5 or so baby rabbits that morning.
My previous dog* loved a piece of rawhide for dessert. More than once I had to reach down into the back of his mouth and pull out a piece that was almost but not quite small enough to swallow. My current dog gets a Costco-branded “Greenie” chew treat for dessert and will never see rawhide.
*That’s not what killed him.
Just to add: beef bones appear to be safe since, when chewed, something about their makeup causes them to break down into little “cubes” as opposed to splintering. The little bits are able to pass through a dog’s system much more easily than a narrow-but-long “splinter”, like often happens with chicken bones.
