REVERE (CBS) – Elias Pacheco-Osario said he’s sorry he chained his dog to a steel rod at a Revere beach last weekend and, as State Police said, left him “to the mercy of the next high tide.”

Pacheco-Osario, 27, of Revere, pleaded not guilty to animal cruelty at his arraignment Tuesday in Chelsea District Court and was released on $340 cash bail.

His dog “Killer,” a 50-pound pit bull mix, was found chained to a rebar rod on Short Beach in Revere on Sunday. There was also a heavy rock attached to the thick metal chain to prevent him from escaping.

“The dog was at risk of drowning in a couple of hours if he hadn’t been found,” State Police said, noting that during certain parts of the day, that portion of the beach is completely submerged by the rising tide.

The dog was rescued and is now being cared for at Ocean View Kennels in Revere. Police reviewed surveillance video from the area and later arrested Pacheco-Osario.

Speaking partly in Spanish, he told reporters after his arraignment Tuesday that he got the dog from a friend in Virginia just six months ago, but was having issues with him and couldn’t get a shelter to take him.

“I’m sorry,” Pacheco-Osario said to reporters, apologizing for what he did.

He is due back in court November 3 for another hearing in the case.

The dog has been renamed Carmelo and is in good health. He will visit the vet on Wednesday.

“His canvas is young so his canvas is still pretty blank so now he can just make his own beautiful story,” said a worker at Ocean View Kennels.
