If you read the back of your dog food bag, it will tell you how much food she is supposed to have for her weight. DO NOT feed her any more than this. Dogs don't beg because they're hungry. They beg because what we're doing, they want to be a part of. It makes her feel a little more like "part of the pack" the best option is to feed her her kibble while you are eating dinner or restrict her to a certain part of the house. Your dog is not in charge. You are.
At the table or everywhere? Maybe she isn't getting enough food to satisfy her growing appetite. Remember that is the key word...GROWING!!! Try giving her a little more food or break up her feeding....one at morning and then once at your dinner time. That way she is occupied while you and your family are eating dinner!!
