I mean I have a greyhound who can countersurf, you just put baby gates around the kitchen and food. Keeping stuff out of snoot height/range removes most issues.
Part of it is training them that it isn’t an appropriate thing to do. It usually helps that if they behave (and we’re eating something the pup can safely have) they get a bit of food as a treat.
Training is a must and especially with a dog that big you need to make sure they know what is expected and appropriate. Doing that sets them up for success and makes it much easier to care for them overall.
When my aunt had a puppy, she set up a barrier to prevent the dog from going upstairs. It was low enough for humans to step over, but the puppy couldn’t get over it. Amusingly, as the dog grew up, it never seemed to occur to it that it could now step over the barrier without much fuss.
We used to be able to put up a blanket “wall” across two chairs to stop the dogs from crossing. It took them a few years to realize they could simply walk through/under the blanket.
I have an Akita that can do the same and is (mostly) very good about asking for permission / knowing he needs to be handed food.
I do feel like smaller dogs generally get minimal or zero training because people know they can just pick them up or otherwise stop them and it makes pet ownership worse for everyone involved.
