The sad sight of a male pit bull mourning by the side of his dead partner has moved many to tears after it was posted to Facebook.

On Friday, the female pit bull was killed by a car on South 16th Street in Phoenix, but her partner refused to abandon her.

The male dog stayed by her side for more than 14 hours before Animal Control removed her body and now, they say, he is still so depressed he may not be able to find a home to adopt him.
