The girl, identified as Ashu, was playing near her house on the outskirts of Bhindran village on Wednesday evening when the dogs attacked her, Deputy Inspector of Police (Rural) Sandeep Wadhera said.
The dogs caught Ashu by the neck and dragged her for about 300 metres before mauling her, he added.
A villager, who was passing by on a motorcycle, saw the dogs attacking Ashu and chased away the canines by throwing stones at them, the senior police official said.
The man also informed the girl's parents, who had gone to fetch fodder from the fields. Ashu was taken to Sangrur Civil Hospital. She was later referred to Rajindra Hospital in Patiala where she succumbed to injuries, Mr Wadhera added.
Residents living in central and southern parts of Chandigarh complained that a growing number of stray dogs in parks and gardens had made it difficult for people and children to use them.
"I fear sending my children to play outside. The parks near our home are full of stray dogs and we cannot allow the children to go out without an adult accompanying them," a resident, Arun Kumar, said.
