my kid's rabbit and our lab puppy

My daughter got a rabbit for her birthday and named him Moo Dang. Our lab puppy Namkhang thinks the rabbit is a toy. The first two days he kept staring at the cage, tail going, not understanding why we don't let him play. Rabbit basics we learned: he needs unlimited hay, not just pellets, and a big cage so he can hop. Keep him away from the aircon directly. Chiang Mai nights can be cold but the days are hot. Check his teeth too. Namkhang lies next to the cage now, which is not bad.
