I am trying not to give my dog table scrap because he will start begging when he sees someone eats. My sons however, loves to sneak him a bit here and there.

When we eat, I gave him his bone and told him to go away to eat his. I can understand why he likes to eat with us though, as he is a part of the family.

Well, it’s natural not just with dogs but often with cats too. Or at least, they will want to see what you are eating. It is important to not let them have anything silly, as their health is on stake with wrong food. I go very carefully and that’s why I give supplements to keep them healthy and on for long life! I have found these best from this article http://www.blackburndistributions.com/blog/pet-supplements/

My dog always seems curious about my food, but I stick to dog food. I think it's more about wanting what I'm having than disliking theirs.
