Christopher Ramirez was found by a landowner near Texas State Highway 249, outside of Magnolia in Montgomery County, said Tim Miller, founder and director of Texas EquuSearch, a search and rescue organization dedicated to searching for missing persons.
Ramirez was reunited with his mother and taken to Texas Children's Hospital to be evaluated. EquuSearch shared a photo of him shirtless in a car, being cradled by a woman, though did not provide further details.
The toddler was found around 11:45 a.m. local time and was dehydrated, Grimes County Sheriff Don Sowell said.
He had said there was no evidence of foul play, and family members were not persons of interest.
According to authorities, Christopher was playing with a neighbor's dog in Plantersville on Wednesday while his mother unloaded groceries from her car. The boy then followed the dog into the woods. The dog returned but the toddler was gone.
