Police raided the home of rapper DMX, and they apparently found 12 neglected dogs and a number of guns.
The pit bulls terriers were not being fed or given water, and have been removed, police said.
No arrests have been made and DMX, 36, said he had not been at the property in Arizona for at least two months.
His lawyer said a caretaker was left in charge and DMX, real name Earl Simmons, was disturbed to hear the animals had not been looked after.
The buried dogs were found when the back yard was dug up. One had apparently been burnt and the cause of death of the others was unknown because the bodies were decomposing.
