Hello, I need some advice. I've had my puppy for 3 weeks and she is now 11 weeks. She usually eats well and finish her meals within 5 to 10 minutes. But since a few days, she is showing no interest in the food we give her, Royal Canin Labrador Puppy. She is currently 8.2kg. But now, i have to leave the feeding bowl near her so that she eventually finish the meal. She drags it for hours and when i shoulf be giving her her next meal, the previous one is still there. Please advise. Thanks.
