13 hours is probably just to long for him. I'd try either feeding him a little later at night or earlier in the morning, maybe both. I've never had problems with Yumi doing this, but Yuri did it a lot as a puppy. He was always a crazy picky eater, so even leaving kibble down for him, he would refuse to eat it and end up sick. Yumi on the other hand has only puked up bile a few times, and it was full of Yuri fur from when he started shedding this spring/summer |
