Would an attack by a pet "Wolf-Dog" support a claim for strict liability?

It appears that the recent popularity over new hybrid dog breeds has spawned a more dangerous market for hybrid dog/wolf pups. Animal groups have expressed concerns about the growing hybrid population, warning that the creatures could present a danger to humans, particularly children, who experts say are seen as "prey" by the animals. In the US, where they have carried out a number of fatal attacks on children, hybrids are banned in some states and in others are only legal once they are five generations removed from wolves. In the United Kingdom the law only requires the dog to be three generations removed from the wild animal. For more on this topic go here and here.
