Her Doggy (1914)

Harshly treated by her stepfather, a little girl lavishes her affections upon a mongrel. A doctor, summering near the farm, wishes to purchase a dog for vivisection and the girl's stepfather offers to sell her pet for five dollars. Panic-stricken, she runs away during the night, and is found next morning by the doctor's wife, fast asleep in a field with the dog.
