*sighs* Muffin ate my lovey-pet Skittles when Muffin first came home. I now keep my birds clipped so they cannot fly (which is what brought on the hunting instinct)

This is not something to be worried about, because dogs are animals. They still have the instincts to survive in the wild, including hunting for meals. Dogs are carnivores. It's very sad when they kill something innocent without reason, but there isn't much you can do.

*hugs to you*
