I just read in the other thread that she ate a large venison roast and organs. Has she had it before? If not I would think it's the roast that's giving her the gas. Next time you may want to cut down on the amount you give her.

My dogs get gas when they have a large amount of pork (so now I have the butcher cut the pork roasts in 1/4s instead of giving them a whole one at once). I know the first time I gave them a whole one I figured it was okay, because they'd had pork many times before, and they'd eaten large things like whole chickens. Boy was I wrong! Some of the worst gas and burps I've ever smelt! And it was a rainy night, the power went out, so we decided to go drive around with the dogs to find which power line was down and call the company ... bad idea! They stunk up the car big time!!

So basically I try to prevent gas by knowing what they can and can't handle. "Know thy dog". hehehe
