Pearl Radcliff, 84, disappeared on Wednesday and was last seen in the 11800 block of Acadian Drive in the afternoon. “Pearl is known to take walks with her dogs,” rescue organization Texas EquuSearch said at the time.

Reports suggested that Radcliff suffers from dementia and memory issues. More than 55 million people live with the disease across the globe, and there are nearly 10 million new cases every year, according to the World Health Organization (WHO).

As reported by news outlet KHOU 11, Radcliff had adopted Maximus just over a week before she went missing.

Research shows that going missing is a huge risk when it comes to those suffering with dementia or memory issues.

According to Prof Michael Hornberger from Norwich Medical School at the University of East Anglia (UEA) in England, “around 70 percent of people with dementia may go missing at least once, with some risk of going missing multiple times.”

People with dementia are also more likely to wander in areas where road networks are dense, complicated and disordered, says UEA research.

Radcliff’s nephew Dawne Griffith was alerted to her whereabouts on Friday afternoon just before 5 p.m., according to KHOU 11. The 84-year-old had been taken into Memorial Hermann Southwest Hospital in Houston.

Officials said that Radcliff is doing well, which Griffith confirmed. Before receiving the call, Texas EquuSearch volunteers were heading to Radcliff’s home to aid search efforts.

Radcliff’s dog sticking by her side goes to show just how far the relationship between a dog and its human goes, no matter how new it is.

Earlier this year, a Kansas dog missed its owners so much that it managed to escape out of the kennel while they were away on vacation.

Dexter did the impossible and returned two miles back to his family home, all by himself. Sarah and Jeremy Henson were alerted to movement on their front porch via their doorbell camera system, only to find their pet had returned home to be reunited.

In February, a man’s body was discovered in Arkansas after days of searching, but his pet pit bull was found alive beside its owner, a week after they both went missing.
