Our retreiver loves a good chew. We give her rawhide chews which she loves, they just don't last very long! She has had bones from the pet shop and pets at home have also started selling deer antler which we tried, she absolutely loved it! It didn't splinter at all, lasted for ages and was full of marrow.
We also have nylabones which she loves, never had any trouble so far.
What we don't give her is things like tennis balls and roes etc as she just eats them.
I think, to a certain extent, everything can be pontentially dangerous. I think it can be easy to pander to warnings and stuff but at the end of the day, you can be chewing your dinner and crack a tooth causing a trip to the dentist etc. but you can't not eat because there is a small risk you might choke/get ill/hurt a tooth etc.
