This week, an inquest heard that Galwaywoman Teresa McDonaghâs brutal death could have been avoided, had warnings about how dangerous her sonâs three Presa Canario dogs were been taken seriously. Mrs McDonagh, aged 64, died of âmassiveâ injuries, after she was attacked at her sonâs home in June, 2017. The killer dogs had free rein in father-of-four Martin McDonaghâs property and were described by the local postman as the most vicious dogs he had seen in 25 years.
