PHILADELPHIA (CBS) — It is the tale of one dog with two owners.

Mooka is an eight-year-old Shih Tzu from Mount Airy.

Mooka’s owner Kim Quitman says she let her dog outside for five minutes and he was picked up by someone who took the dog to the Pennsylvania SPCA.

Kim says she called the PSPCA the same day Mooka went missing.

The PSPCA admits it made a mistake and allowed a new family to adopt Mooka four days after he was taken to the shelter.

Quitman told Eyewitness News, “He was then adopted out to this family who refuses to give him back. They had him for one week. I have had my dog since he was two-months-old.”

The PSPCA says the mistake happened when the staff did not check to make sure Mooka was not reported missing before they allowed him to be adopted.

The PSPCA calls the mistake regretful and says it tries to do the best it can with the staff it has.

As of now, Mooka remains in the possession of the family that adopted him.
