The remains were found during a raid on the house last month amid allegations of animal neglect.
Authorities also found 12 live pit bulls, a number of weapons and about a quarter-ounce of marijuana.
No charges have been filed against DMX or anyone else, but the Maricopa County sheriff says that could change. The sheriff says, "Someone's going to have to pay for this."
A lawyer for DMX says the rapper hasn't been at the home for months and was paying caretakers and veterinarians to care for the animals. He says there's nothing to connect his client to animal abuse, suggesting authorities are preying on DMX's celebrity.
