Poor Ozzie Osborn. Something ate his favorite chihuahua. Thinking that it might be a coyote, he threw a poisoned dead chicken over the fence. But, nothing touched the chicken.
Of course, given the small size of the dog, any predator could have eaten it. It may have even fallen victim to a hawk attack. He will probably never know. He best bet is to keep a closer watch on his dogs.
Ozzie will probably be in therapy for years because of this event.
