I've been browsing PetTalk for a long time, but have been motivated to register so I could offer my suggestion for how to feed poultry bones to dogs.

I would never give raw chicken bones to dogs - not worth the risk. However, our family eats a lot of chicken, so I save all the bones and pressure cook them for several hours. When even the toughest bone can be crushed in my fingers, they are ready to add to my dogs' dinners.

If you don't have a pressure cooker, the bones can be simmered for a long time to achieve the same result. I frequently simmer a potfull all day, turn it off at night, and start it up again the next morning, adding water when necessary. Again, when the bones crush easily, they are ready for use.

The bones can be collected in a bag in the freezer until there are enough for a batch, and later, the crushed bones can be frozen in small containers.

Hope this helps!
