Leimome Cheeks, 62, was arrested on Saturday and charged with two counts of child endangerment.
Cheeks told police that she placed the children in the kennels, but she made sure to check on them periodically. The temperature in Memphis on Saturday got up to 95 degrees.
Footage of the incident, which was sent to police by an anonymous bystander, shows the moment the woman let her grandchildren out of the kennels, which were placed in the back of her vehicle. Another neighbor told Fox 13 Cheeks "loves her grandkids" and that they were "always outside playing with the dogs and stuff".
Neighbors of Leimome Cheeks expressed shock, saying she was a 'very nice woman'.
She admitted driving them for about 35 minutes. Cheeks has been identified as the childrens' grandmother, according to Commercial Appeal.
