$2,000 is now being offered in this case, an amount that has doubled during the past few days.
Police say they have two 'persons of interest' in this case so far. They've interviewed one and are still looking for another.
The body of the dog, a three-year-old Siberian Husky named 'Chico,' was found by the back door of Sherri Verden's home in the 200 block of Byberry Road on Sunday night.
The dog was cut in half before being left by Verden's home.
Verden suspects the dog's killing is the work of a former neighbor who has been harassing her for years; throwing motor oil at her home and committing other acts of vandalism that she has reported to police.
Chico belonged to a family who lives on Haldeman Avenue. They said their pet ran away around 9:00 p.m. Sunday and were still looking for him when they got the call from the SPCA.
Anyone with information is being asked to call the SPCA hotline at 215-426-6300.
