because she is a senior dog, trying to "re-train" her may be hard dogs can be like kids.. and when they get old they turn in to seniors with dementia. Restrict her access to the kitchen with baby gates you can get them free off of freecycle. then you want to leave things out on the counter to defrost for the day, dont leave them on the counter.. put them somewhere safe instead like in the oven or in the microwave (dont turn them on just use it a safe place). I have used dollar store mouse traps to keep my pets (cats included) off the counters. The springs in the $ store ones are not strong enough to hurt them just give them a fright. As for wacking them with a rolled up news paper, thats just asking for problems. If she was a rescue to begin with then this may bring on some unwanted aggression.
