My dog just ate a pork rib bone all in one?

i dropped it on the floor, didnt realise i did- i ws throwing last nights food in the bin and she gobbled it right up! she as a 10 year old staffordshire bull terrier and was about an inch long....will she need to go to the vets or should we just leave her to digest it or what? I cant believe shes done it! she is so well trained she never eats until we tell her to, no im a little worried? It was a cooked bone aswell, and i heard you cant give you dog and cooked meat- cos it splinters, but because she ate it in one will it not do that?
