She has experienced fireworks before and seemed allright last time im bascly seeking somethat that she can really get her teath into that will keep her really occupied what are the most favourite types of bones/chews for your dogs??

Huge knuckle bones

Marrowbones and beef ribs

Just consider whether she's used to pork or if it might cause an upset tum, having that amount in one go.
One thing that lasts mine a long time is whole rabbit - often feed it still frozen, they get half each, and takes them a good while to get through
