WHY?

Must FFIL feed the dog table food, especially stuff with sauces? He is the absolute worst about it and the dog gets sick all the time. This morning I woke up and saw barf on the carpet and I was the only one home to clean it up! And he feeds her from the table so that when I sit down to eat the dog comes over to me and begs. I feel so bad when they have company because she does this to them to and I think it's so inappropriate!!!
