Managers say damage to a gate, cause by Storm Ciara, allowed the canines to break into a neighbouring pen and attack deer and sheep last Sunday.
Its understood that strong wings and stormy weather damaged a gate and African Wild Dogs managed to escape for their pen at the Safari Park in Bewdley.
A spokesperson from West Midland Safari Park said: “Sadly, we can confirm that in the early hours of 9 February, 12 African Wild Dogs entered a neighbouring compound where a variety of Persian fallow deer and Barbary sheep were housed.
"Six deer and 10 sheep were unfortunately killed in the incident. The wild dogs were returned to their compound unharmed. The wild dogs entered the neighbouring compound through a gated entrance which had been damaged in the storm which hit Worcestershire earlier that morning.
"At no point was there a risk to public safety and there was no danger of any animals escaping the Park’s perimeter fencing. Given their personal attachment to our animals, our staff are extremely saddened by the incident.”
