A pet parrot accidentally poisoned(使中毒) three dogs by mimicking their owner’s voice and feeding them grapes, which are poisonous to dogs. Grapes contain a substance which can cause renal failure in dogs, and can quickly kill them.

The parrot threw the fruit to the dogs while Mrs. Finch was out with her family for the afternoon. When she arrived home, the three dogs had already become unwell. Mrs. Finch noticed some grapes were missing from the fruit bowl and, realizing what had happened, quickly took all three dogs to Portland Vets.

Mrs. Finch, a housewife, said, “Peaches flies freely around the house but returns to her cage when I’m not home. She’s a good mimic and she must have called each dog over by name to be fed and then dropped the grapes in front of them from her cage.”

“It was a worrying time while they were being treated but I’m so grateful to the team at Portland Vets and it’s great to have them safely home. Grapes are now banned(禁止) from the house,” Mrs. Finch said.

Vet Anna Garvey, who treated the dogs, said, “In cases of poisoning, speed of response is really important so Mrs. Finch did the right thing coming to us quickly. It meant we could flush out most of the toxins before they had a chance to cause serious harm to the dogs.
