In an extinct Australian Aboriginal language, Mbabaram, the word for "Dog" is almost exactly the same as the English word for "Dog". The similarity is a complete coincidence.
Interesting question, I hadn't thought about that. I assume they mean dingos.
"Australia’s Indigenous community has had a long relationship with dogs, dating back to the dog’s ancestor, the dingo. Dingo fossils in Australia date back thousands of years, and the first British settlers in 1788 recorded dingoes living with Indigenous Australians"
