Any advice, please?

It's when I'm making our dinner. She'd be in the living room and would perk up when the smell hits her and she'd run. I just wonder if who ever had her before was nasty to her when trying to keep her out of the kitchen

And you're probably right, she may have been a hunting dog, if not then an outside dog. She found some rabbits behind our shed and went nuts! We have to keep her tethered to keep her from going back there, and from digging into our neighbors yard (she loves their puppy!).

I had a Beagle before, but raiser her from a puppy. She just passed away in December. She was very loyal to not only me, but her "sister" as well. ^_^

And just a warning, I did get a ton of pictures over the last two weeks, so there's plenty once I get them off the camera

Thank you all so much for the advice!

Cant wait for the photos Have you tried asking the rescue where you got her from for advice? maybe they had a routine that she was used to?

Your dog has no idea of what is ok and what is not, it appears that the previous owner has made a lasting impression on the dog.
Your dog instinctively knows that dinner time is off limits and out she runs!
Use the old method of good behavoir receives a reward, be it a scooby snack or milkbone. Friendship and love cures all wounds and the hurt a dog feels to be a stray. Praise is another good incentive for your dog to be good.
After some time has passed you'll find that your dog has over came the problems that bug you as well.
Don't give up you can do it!
Without you, the dog is unwanted once more..
