When I think "table food", I think about all the times I saw my grandparents scrape their plates after eating and feed that stuff to the dogs. Tatum does not get table food, never has, so also she does not beg at the table. Sometimes after we eat dinner and we're all still sitting around the table, she comes up to the side of my chair wanting to get up. She just sits on my lap because she wants to join us. Doesn't even give the food on the table a second glance. Now, one time years ago, my dad gave her a taste of some cherry pie from his plate - off his finger. It took a very long time to break her of the habit of begging from him (and only him). He didn't visit for meals very often but Tatum did know that hey, that guy will give me something. They are smart!
There are a lot of people on YT that feed fruit and chicken (no skin) and rice for certain reasons. We stick with good quality dry dog food, bully sticks on occasion and Cheerios for treats. They are very low fat (and yes, cheap!).... she gets them for pottying outside and sometimes just to do tricks.
