With no sheep around, Solo the Border Collie spends his time herding tigers, hyenas and jackals at The Seaview Lion Park in South Africa.
The four-and-a-half-year-old dog grew up alongside the Siberian big cats, and considers them part of his pack.
Despite the tigers' killer strength, Solo has no problem showing who's boss.
Ashley Gombert, the General Manager of Seaview Lion Park says Solo's skills come in very handy.
Border collies are known for their high energy levels and organisational abilities that are normally put to use herding flocks of sheep.
