An infant girl in Wisconsin suffered serious injuries after she was attacked by her grandmother's pet pit bull, authorities said. The incident took place Wednesday afternoon at a Milwaukee home.

According to local media, which cited the girl's mother, the dog attacked the baby without provocation in the living room of the house. The dog also attacked the child's grandmother, who tried to intervene.

Family members were able to stop the 5-year-old pit bull after the child's uncle struck it with a cast-iron skillet.

"Basically, with the help of my brother, because he had to get a cast-iron skillet, sad to say, that's the only thing, and my brother's able to subdue him off of my mom to throw him in our extra bedroom. That's the only thing that stopped it (the dog), and he was still in there going crazy," the girl's mother said, according to WISN.

Emergency responders arrived at the scene and rushed the infant to Children’s Wisconsin. The grandmother, whose injuries were not considered life-threatening, was treated at Froedtert Hospital.

Local police and animal control officer wrangled the dog into an animal shelter van. The dog had blood in its mouth and on its neck. The dog was transported to a dog shelter.

In another incident, a three-year-old girl and her grandmother were attacked by a pit bull during an evening walk in Markham, Illinois.

Speaking to ABC7 Eyewitness News, Gloria McIntosh said she stepped out of her home with her granddaughter and as they reached the corner, they saw the canine coming towards them. McIntosh said she believes the pit bull escaped from a home when a little kid opened the door.

"This pit bull ran up to me and he was trying to grab the baby. So I grabbed her and picked her up and put her over my head. He was jumping, trying to grab her by the legs. He scratched her arms. The dog grabbed me by the leg, bit me a couple of times. I fell to the ground. I fell to the ground and was covering her," she said.

Neighbors rushed to help them. They pulled the dog away and helped McIntosh to her feet following which they called 911.

"Police did ask the people did the dog have rabies shots and they said yeah, but I was just surprise they didn't move the dog," she said.
