The owners of a small dog nearly ripped in two by a bull mastiff say they feel partly responsible for the mauling.
Mt Eden secondhand trader Allison Doody said she should have called ahead to check the nature of the big dog before taking her dog Shortie to a friend's barbecue last week.
The small affenpinscher was lucky to survive the attack, which left him with a shredded rib cage, split muscles and organs hanging outside his body.
Later that day, a child arrived at the house where the mauling occurred and was allowed to cuddle the big dog, as it licked her face. The father was warned what the dog had done earlier but he was unconcerned.
Doody described Shortie's wounds as horrendous.
