WEST ISLIP, N.Y. (CBSNewYork/AP) —  The SPCA is investigating after authorities retrieved the body of a dog chained to a cement block from a canal on Long Island.

A resident discovered the female Rottweiler mix in the canal behind his house around 10 a.m. Thursday, the SPCA said. Authorities believe she may have been dead about five days.

A preliminary inspection did not reveal any obvious abuse or trauma, according to the SPCA.

The black-and-tan dog appeared to be about 7 years old.

A necropsy will be performed Friday to determine cause of death.

“If in fact this dog was put in there alive it would certainly be a heinous crime to say the least, very disturbing,” SPCA Chief Roy Gross told 1010 WINS. “If in fact it was alive, we’d like to certainly apprehend the person responsible for this.”

Anyone with information is being asked to call the SPCA at 631-382-7722.
