Most dogs are physically or behaviourally incapable of killing livestock.
All breeds and sizes of dogs, from Silky Terriers to Great Danes have been caught attacking livestock. Dogs as young as 3 months of age and as old as 12 years, unsterilised and sterilised dogs of both sexes, dogs with three legs, no teeth and with the best pedigree, have been involved. MYTH - Packs of wild or stray dogs are responsible. A dog may attack on its own, with another dog from the same household or in the company of one or two dogs it associates with. MYTH - Only savage dogs kill livestock.
