You realize the importance of securely containing dogs... so I'll not harp.
But for your sake, and your dog's, I'd immediately physically contain your dog. Then start electric collar training, but that takes time to be a trusted alternative. All it takes is some high level prey drive to kick in (ooh!!! Squirell@!!! Must chase squirrel) and in a second the dog runs through the invisible barrier with no more deterrent to not keep going. Then the doggie ADD sets in and next thing you know your pooch is wandering the local neighborhood till a sane thought or hunger prompts pooch to head home or animal control picks up a new catch.
Depending on where you live, the conversation the farmer had with you may be more than plenty to legally allow him to shoot your dog if it trespasses again- even if it's not caught in the act. Some places don't even require owner notification. May not be fair if your dog didn't do it, but it is his right to protect his livestock.
