hmmm...my vet gave me some advice when I bought my pups in for their first examination. He said, "Chicken bones are fine. These days, chickens are culled at very young ages, and their bones are soft. Raw or cooked; I can eat them without problems; and if i can eat them, a dog can do so easily." I have to say, my OH eats chook bones happily - but then again, he thinks he's a macho cave man. (I'm also a bit concerned about a vet that eats raw chicken, but I guess everyone has their preferences! LOL )!!
I would say, watch what you give them. We fuss over whether chook/lamb/other meat is ok; yet i know of dogs who have eaten socks and all sorts of things! - my sister's border collie pup ATE the bumper bar of her new car!
