That said, we used to give our dogs American-made rawhide bones all the time. For years and years, our dogs would get new bones basically every week (because they never lasted much longer than that.) Never had a problem. Never had a dog choke on the pieces and not one of them ever had a blockage.
Same here.
The reason why I would be careful about the brand of rawhide I buy is because I freak out about my dog eating something that had formaldehyde on it! Also some places may treat the rawhide in other chemicals (to clean it). That's too many toxins going into your dog's mouth.
If your dog gets bones regularly, he's more likely to be a casual and slow chewer and won't chomp big pieces down in one sitting. And they will chew on the pieces they do eat.
That said, if your dog is eating a bone in one sitting - then I probably would go and look for something that is more durable or something that is more edible (easily broken down by body).
I can't think of the brandname atm because I haven't bought these in a while, but you can pick them up at the petstore or places like Target. They are big and have a "knuckle end". Not greenies, but I think they are made from veggies and other edible products (I'll have to google later). We used to get these as a special treat for our previous dogs, though Jacks has never had one.
These bones would last about half an hour with our guys - if that. But it was good for calming down chewing angst.
ETA - Booda bones!
But there are plenty of other brands out there too.
