The reason why a dog bites a chicken to death is because a dog’s nature is to hunt, so after seeing a chicken, it will catch the chicken and may even bite the chicken to death. The reason why the dog does not eat the chicken after killing it may be because the dog is not hungry or the dog does not like to eat raw food. This is because after being domesticated, dogs now like to eat cooked food, so they are not interested in raw chicken.
Tip:
It is best not to feed your dog raw chicken, because raw chicken may contain parasites and bacteria, which will affect your dog’s health after eating it.
