I just got my first foster, Nina, a few days ago and I'm a little nervous that she's not eating enough. She ate fine the first day at my home but for the past 2 or 3 days, she's only been eating about 1 cup per day. She didn't eat anything at all today. I'm giving her NutroMax Large Breed.. I don't know if she doesn't like the brand or just isn't hungry... When I give her a treat to go in her crate at night she eats it right away. She's a big girl at 150 lbs, so she could afford to lose a little weight, but I don't think not eating is the way to do it! I've been walking her at least 30 minutes per day and she's been going to the bathroom regularly... so I don't know what's wrong! Any ideas on what I should do??? THANKS!
