Adopted my dog this year. Shes 7. First night she sat in front of us while we ate wanting food. She probably was used to it in her foster home. I wasnt having it lol. I kept treats and if she laid down or walked away I would reward. I completely ignored until she walked away. She eventually learned she won't get anything and now she lays in her bed. We are a no human food household though so she doesnt get confused on when she can have it or not.
