GILBERT, AZ - Four dogs were impounded after a 2-year-old was killed, and his babysitter significantly injured, when they were attacked Sunday in Gilbert .
Melissa Gable, spokeswoman for Maricopa County Animal Care and Control, said two male and two female dogs of "some sort of pit bull mix" were brought to the group's West facility.
Gable said the dogs are not licensed and do not show any documented history of past violence or public complaints.
According to police reports, the attack occurred at the home of a 28-year-old woman who was babysitting the toddler near Germann and Val Vista roads Saturday afternoon.
The boy was taken to Gilbert Mercy Hospital where he later died, said officials.
Gilbert police Sgt. Jesse Sanger said the babysitter was watching five children at her home while their parents were out of town. The children range is age from 2 1/2 to 9 years old.
Sanger said three of the dogs began to fight and the babysitter stepped in to try and break it up. At some point the toddler became involved in the fray and was gravely injured.
The babysitter remained hospitalized and under heavy sedation Monday.
William Conway, who has owned and sold pit bulls in the Valley for more than 10 years, said it's always important to keep safety in mind if you're the owner of one of these dogs.
"You just want to monitor the dog and make sure it's not expressing any sort of aggressive behavior towards another dog or a human being," said Conway.
All of the dogs are being held in a 10-day quarantine for rabies, which is standard for all dog bites, said Gable. They will be checked for rabies by veterinarians
