We would give our newfies beef knuckle bones and they would chew away on them for days until they licked all the marrow out. I have only known of one dog that was given chicken bones (hubby's), but I put a stop to it.
There is often something to the "old wives tales."
Addition: Update on my rottie's diet. I eliminated all table scraps and fat from my fat boy's meals and he is already beginning to slim down a bit. Better yet, he is walking with greater ease and joined in a rabbit chase or two.
