Three dogs treated for injuries after being baited with nails in Botany Cruz and Stella ingested nails. Stella had hers surgically removed. A SIX-month-old puppy is lucky to be alive after being baited with at least 40 nails in an act of animal cruelty, according to the owner. Two of Anne Williamson's three dogs were rushed to surgery after eating the nails, which she believed was a deliberate attempt to kill them. Mrs Williamson, of Botany, said the first she knew of the attack when she saw her puppy Tilly had vomited 31 nails. The 31 nails Tilly vomited and a container of the nails surgically removed. At the Sydney Animal Hospital vets removed 8 more nails from Tilly, who is still at the hospital waiting for at least one more nail to pass from her bowel. X-rays confirmed Ms Williamson's two other dogs, one-year-old Labrador, Cruz, and six-year-old Labrador cross Stella, also had nails inside them, with Stella requiring surgery. Mrs Williamson fears someone spiked her beloved pets' food to deliberately harm them. "A dog might eat a nail accidentally, but no dog would accidentally eat 40 nails," she said. And all three dogs don't eat nails on the same day. I'm so angry; it is so cruel someone has fed my dogs nails. Head vet at Struggletown Veterinary Hospital in Randwick, Simon Roberts, said it was highly unusual for a dog to swallow one nail, let alone several. ``You could understand one or two nails, but it makes me think someone has wrapped up nails in pieces of meat," Dr Roberts said. It's bizarre. I would be suspicious before I would think it was a one-off occurrence. Mrs Williamson said she searched her gardens and fence, but there was nowhere her dogs could have found and eaten the nails. Ms Williamson contacted Botany Bay Police who are investigating her claims.
