Kito's took a while to grow back too. I didn't want a bald tummy dog either, and I hated looking at it, but it eventually grew back. Honey's probably grew back so fast because pom's hair grows so quickly. When Cody had a bald spot on his back, the vet suggested giving Cody melatonin (people dose--you can get it at walmart), to help his hair grow back, and it did. I would check with the vet first, but maybe you could try that.
