I can see you with a pet honey badger. Deploying the beast down a PD hole like an atomic ferret. There's a guy in Ohio training them who has a bunch of good videos including walking them on leash and retrieving.
This is my vote! The ultimate multi-purpose pet... PD eradicator and duck retriever, then curled up in the bed with you at night!
I don't need you two ganging up on me with good ideas. I was thinking some sort of little dog like a terrier, but that thing would probably dig holes worse than the badger. I'd be fixing dog diggings, not vermin diggings.
The vermin don't seem too hard to temporarily eradicate, it is that the legacy tunnels that they reopen. You guys need to put your creative minds towards finding a way to close up the tunnels. I was thinking a redi-mix truck with a thin mix.
