Harris County Constable Ted Heap reported early morning Friday that Katy-area mother Sherry Noppe and her dog were found.
PC. Heap said the discovery of the woman came after hearing barking from her dog, Max. approximately at 3 a.m. Friday.
The 63-year-old was found deep in the woods of George Bush Park.
Noppe had been missing since Tuesday.
"It's a small miracle that she has been found alive after being missing for so long," said PC Heap. "Thank you to Texas EquuSearch along with the army of volunteers and multiple law enforcement agencies who never gave up in her search."
Authorities in Texas are searching for 63-year-old Sherry Noppe and her dog, Max, and say they have no leads at this time.
The Katy area mother was last seen around 2:20 p.m. on Tuesday walking her dog, a large black lab, near Fry Road and Highland Knolls.
She is about 5 feet 7 inches tall with a slim build, according to officials; and was seen wearing a blue-green short-sleeve top, blue shorts, and white sneakers at the time of her disappearance. Her dog was sporting a pink collar at the time.
Anyone with information about her whereabouts is asked to call 281-463-6666 or Texas EquuSearch at 281-309-9500.
