Just curious, I had a dog when I was a small child, and I think it died when I was about 12, and I’ve never had a dog since then? But as far as “begging at the table” or “Asking for handouts”? What Breed of dog would LEAST be likely to do this? Or would not bother you while you are eating? I agree I would do my part and feed the dog twice a day? But if it keeps asking for more food, what do you do then!!
I doubt it's breed specific, any well trained pupper will go lay down elsewhere when human food is happening. When I had my boys (dogs) they knew which food was theirs, which belonged to the cats, or was human food and they only ate theirs. I fed them once a day, their recommended amount and they were good.
