Heck no, it doesn't matter what type of bones and beef went into the pot, I use a mixture of everything I get from a whole steer, from the trimmed shortrib bones to the bigger leg sections.

You could have simmered it all night, although you'd have to make sure you have plenty of liquid and your stock might not be as clear because of the vegetables and bone marrow, etc. Simmering that long would probably just disintegrate those items and the solids would disperse into the stock.

Some people strain the broth to make it more clear, I don't bother. The last batch I made is so thick it's gelatinous, the girls call it "cow jello" and I had big beefy bones, I think I simmered it 5 or 6 hours for about 20 pounds of bones, in my electric roaster because I don't own a stockpot big enough for that many bones.

Thanks Annie, that is about what I thought. The broth is already fairly gelatinous as is and I wouldn't want it more so. I did strain it three times and it is clear- which I prefer.

If it's fit for human consumption then why would it be labeled as dog food? It's not like dogs object to eating human food. Here's a quote from ritaotay on this same topic in another (linked) thread:

"Years ago my Mother would buy soup bones from a local butcher who bought whole animals from the local stock yards... On one visit to the butchers shop she noticed a sign for Free dog bones and asked for a few pounds of beef dog bones... The man behind the counter told her they were NOT for human consumption for various reasons, most weren't properly refrigerated, they were all dumped in one container ( beef, pork, lamb, veal... ) some had fallen on the floor or fished out of the trash... Granted most stores today wouldn't take the chance of selling contaminated bones but... Better safe than sorry, ask if they ARE fit for human consumption."

p.s. Any particular reason to supervise dogs eating bones?

Here is a link that might be useful: fit for human consumption?

A lot of people feed their dogs raw now and others feed bones on a regular basis, especially marrow bones. When they call them dog bones it generally means they are big enough so that the dogs can't swallow them whole. Dog safety.. smiles.

I always asked Carl to cut the bones especially for my WonderWeiner. Carl would cut sections of the leg bones so that he could get the marrow out without having a bone small enough to swallow, and he always trimmed the ribs so WW could have the bones.

I also remember going to Mondrella's Meat Market when I was a kid and asking for bones for the dog, Mr. Mondrella always wrapped up the bones for me and I took them home where Grandma made soup from them. Then the dogs got them, LOL. Waste not, want not, Grandma said...

The broth - 12 cups- is now frozen and ready for my next pot of French onion soup. But, foodonastump, that quote was disturbing. I'm pretty sure these bones are fine, they were in the meat section at the grocery store and the store is annoyingly adamant about throwing out (and not selling) all out of date stuff so I would think the bones were labeled "dog bones" to cater to particular customers and not because they were crap.
And, as Annie mentions, many of them were cut so the marrow was easily available.
Whoda thought such a little thing would cause me anxiety?

My dogs eat better than I do most of the time. I can't police them from eating dead stuff in the woods though.

Yeah, on further thought I'd have to think that in this day and age it would have to be pretty clearly marked if it wasn't good. Why not just call the store and ask? Sorry to cause you anxiety - I'm sure you're fine.
