How do you stop a small terrier from going down rabbit holes?

Terriers tend to be very persistent in this kind of behavior. Here are some tips that might help:

1. Block the Holes: Cover or block any existing rabbit holes on your property. Ensure the covers or barriers are sturdy enough to withstand the terrier's digging attempts.

2. Scent Deterrents: Certain smells, like strong spices, vinegar, or garlic, are usually unappealing to dogs. Place some of these substances near the rabbit hole to discourage the terrier from digging there.

3. Supervise and Distract: Keep an eye on your terrier while it's outside, and try to distract it if you see it heading towards the rabbit holes. Offer toys, play fetch, or use other forms of positive reinforcement to keep it engaged.

4. Positive Reinforcement: When your terrier refrains from digging, praise and reward it. Show your approval with treats or petting to reinforce good behavior.

5. Set Boundaries: Establish clear boundaries for your dog, showing where it's allowed and not allowed to go. Use physical barriers like fences, training flags, or barriers to indicate the boundaries.

6. Seek Professional Help: If the behavior persists despite your efforts, consider seeking advice from a professional dog trainer who specializes in behavioral modification. They can help you develop a tailored training plan to address the issue.

Remember, terriers have strong instincts and may attempt to dig even when you're not around. Patience and consistent training are key in deterring this behavior.
