Unaware that Zara was zeus's sister we bought both dogs, also having Troy the boerboel already at home. It was a wonderful trio whereby the boerboel does the intimidation with his size and the two german shepherds does the smart work and pursuit. Until zara and Troy had the fight with parvovirus which they didn't win, leaving just Zeus, the beautiful tale which began happily ended in loneliness. I hope he overcomes the loneliness and be an active energetic dog as always.
