She is about 1 year old and she is a very picky eater. She begs when I have food at the table, but I do not want to give her table food. She is a rescued dog and I have no idea what her previous owners fed her. She really does not like dog food, and I have tried almost every brand.
You can stop buying new kinds of food (thank goodness, right?) and stick to your guns with just one. She will not let herself starve – when it's her regular mealtime, set down her bowl and don't pay any special attention to her. If she doesn't start eating within 2 minutes, up comes the bowl and you wait until next mealtime. No treats and no human food! Be sure to tell your family – if somebody is sneaking her treats, it will make things much harder.
