SPCA officers carried out bags and boxes of evidence from a home in the 2400 block of Wayne Avenue in the city of Coatesville.
Officials say the scene inside was dark and disturbing with elements of witchcraft and the occult on vivid display.
In the living room, investigators say they found two dog skulls and a dog skeleton that had been gold-leafed.
They then walked into the kitchen and found two dog skeletons on the counter and a dog's head in the freezer.
Authorities say the scene was even more sickening when they walked into the home's backyard.
They found dog fragments charred in a fire pit and chicken parts hanging from a tree. Two live chickens and another dog head were also found in the back.
Officials say they found books on witchcraft and the occult, as well as marijuana, a gun, and various knives and machetes.
"We would describe this as just macabre. When you go into a living room and see gold-leafed skulls of dogs, a vertebrae of a dog, and go into the freezer and see the head of a dog, for starters, you know this isn't your ordinary scenario," Richard Britton of the Chester County SPCA said.
The two people taken into custody face numerous charges.
