I know that dogs can't have poultry bones because they splinter, but what about pork? I just made a huge pot of homemade Navy Bean and Ham Soup and I used the huge center bone from my spiral cut Easter Ham for flavor and ham shreds. I've got two bones about 5" long and an inch or so across. Are they safe or should I keep 'em away from Riley and Sasha? They've been dancing around me for two hours waiting for these things, and I don't want to give them out until I know for sure! Thanks for any info!
