We have two stories today of long lost dogs that have been found, and thanks to embedded identification microchips, they were reunited with their families.

A veterinarian says that lost-and-found pooch Rocco is happy and healthy — in spite of having been separated from his Queens family for five years.

Rocco was reunited with his owners after he turned up 850 miles away on July 3 at an animal shelter in Hinesville, Ga. The dog had been tagged with a microchip that was used to identify his owners.

Eleven-year-old Natalie Villacis was still in kindergarten when her beloved dog went missing. She says the dog acts as if “he knew he was home.”

The beagle was taken for a checkup Tuesday at an animal clinic. Veterinarian Dr. Steven Weinstein said Rocco was fine, aside from a scar on his ear and a case of heartworm disease. He prescribed antibiotics to get rid of the parasite.

— In Northfield, Ill., a collie that disappeared during a Memorial Day picnic five years ago has been reunited with his suburban Chicago family.

The dog named Bo was found about 75 miles away at an animal control facility in Rockford. Employees scanned his microchip and contacted the Moeller family of Arlington Heights to tell them he had been found.

The family was living in Northfield when Bo went missing in 2003. On Tuesday, family members had tears in their eyes when they saw Bo again.

Shelter officials say there’s no way to know where the dog has been for the last five years but he was in good condition. They also say his ears perked up when he saw the Moeller family.

— We had the story yesterday about a woman who put a dead rat into food at an upscale restaurant. Today, there is word that a man claims he was nearly cut when he found a knife baked into the bun of a cold-cut 12-inch sandwich he bought at a Subway restaurant in New York City.

John Agnesini says he knew his lunch didn’t taste right. The 27-year-old says he was horrified to find a 7-inch serrated blade in the bread.

He says it was protruding into the half of the sandwich he was about to start chomping on and that it “could’ve slashed” the side of his mouth.

Instead, he says he fell ill with “severe stomach issues” for hours after eating. He attributes it to food poisoning from the embedded blade.
