This is a really fun 16 minute listen to how this precise dog behaviour is exploited to eradicate rats on Lord Howe Island.

They search specifically for dogs obsessed with ball chasing and turn them into rat hunting dogs.

There's funny bit where they talk about finding a dog that had learned how to use the tennis ball firing machine and spent all day chasing a tennis ball and putting it back in the machine which fires the tennis ball in a never ending loop.
