Heidi is underweight, we need to fatten her up. So we made a feeding schedual. She's on two types of dog food (same brand). One flavor is chicken and beef and the other is duck. In the morning she doesn't eat much, so we will give her one cup of duck flavor. Then around 12noon she'll get one cup of each flavor. Around 4:30-5 she gets another one cup of chicken\beef. Then late at night, before we all settle down, she gets two cups again. This is temporary until she fattens up a little. She should be around 95-100 pounds but she's only 86 pounds. It might take a few weeks.
