Louise, a 28-year-old who met the man through working in the horse racing industry, described the relationship as "very on-and-off, not overly serious, very hot and cold".
"It got a bit weird towards the end," she said. "He would throw almost tantrums, throw himself on the ground and carry on - I thought, 'Oh, I don't like this'."
The man also felt slighted that Indie did not like him during the months they were together. "I said, 'What are you talking about? She likes everyone', but he said, 'No, she growls at me'," Louise said.
Indie was killed by the man as revenge for the relationship ending. The story was told with a warning that it contains graphic content.
The case draws attention to a documented method of coercive control as part of family violence: harming, abusing or threatening to hurt pets. In Australia, however, there is a shortage of data on the practice.
