I have 8 dogs kenneled together and have no problems at all. 3 greyhounds a borzoi, grey/whippet/beddy, beddy/whippet, bitza, and a whippet hybrid. 2 ENTIRE dogs, 3 ENTIRE bitches, 2 SPAYED bitches and 1 CASTRATED dog. The 2 intact dogs are father and son and have never argued, when 1 of the bitches comes in heat, she comes in doors, so males don't have a reason to fight. They all get fed together, there may be a few growls from the older members but they are a pack with a firm set hierarchy.
