A guard dog at a Fort Worth tire shop did little to deter overnight thieves; they simply stole the dog, too.

Owner Nayer Younis said thieves have hit his shop five times, despite his security measures, which included adding barbed wire.

The dog was taken two weeks ago.

“It makes me sick, but life goes on," Younis said. "I have two dogs now, so I hope they do [help]."

Since December, Goody’s Cars and Tires, in the 3100 block of North Beach Street in northeast Fort Worth, has been burglarized three times and vehicles have been stolen from the property. Younis said he has captured all the incidents on surveillance camera.

No arrests have been made.

He said the security tapes show two large men. In February, they used bolt cutters to get through the front gate and grabbed a battery and put it in a truck that didn’t have one, he said.

The shop owner believes the thieves have been watching his shop.

A truck that was stolen from the site in December was found and returned by police, but the same truck was taken again in February.

"It makes me mad, miserable," Younis said. "Why are people doing this? It’s not a good feeling."

The robberies frustrate Younis, an Iraqi immigrant, who has been a victim of crime previously. He said he was robbed at gunpoint six months after moving to the U.S. in 1994 while working at an Irving Taco Bell.

Younis, who said he barely knew English at the time, was frightened as the man shoved a gun to his head and demanded that he get on his knees. The man took his wallet before forcing Younis and two female co-workers into a freezer.

Almost 22 years later, the business owner still faces the same enemy: criminals.

"Hopefully, it will stop or else I will have to come up with a better idea and go from there," Younis said.
