📡 What Is an Invisible Fence?

An invisible or wireless fence is a containment system designed to keep your dog within a specific boundary—without a physical barrier. It typically uses a buried wire (in-ground) or GPS signal (wireless) paired with a collar receiver.

• 🚫 Traditional systems use electric shock to correct dogs when they cross boundaries.
• 🛰️ Newer models use GPS or vibration cues—no wires required.

⚖️ Legal & Ethical Statement

In this state, I, Dr Duncan Houston, do not recommend the use of electric shock collars—they are illegal in Australia.

Instead, we recommend a gentle, effective solution: the Ask A Vet Premium GPS Health Tracker. This device uses:

• 🔊 Sound alerts
• 📳 Gentle vibration
• 🎤 Pre-recorded voice commands

This approach reinforces boundaries without pain, fear, or long-term behavioral fallout.

🚨 Dangers of Electric Shock Collars

• ⚠️ Can cause stress, fear, and anxiety
• 🐶 May increase aggression in some dogs
• 🧠 Can break trust between dog and handler
• ❌ Illegal or banned in multiple countries and regions

🛠️ Safer Invisible Fence Alternatives

Our top choice: GPS-based tracking collars like the Ask A Vet system.

• 🎯 Define safe zones using your smartphone
• 📍 Get alerts if your dog leaves the boundary
• 📢 Cue your dog using voice, sound, or vibration—not shocks

📋 How to Use a Humane Containment System

1. 1. Start with basic recall training: Your dog should reliably come when called before using any boundary system.
2. 2. Walk the boundary together: Reinforce the perimeter daily using treats and praise.
3. 3. Use consistent audio/vibration cues: Let your dog associate the alert with changing direction or returning.
4. 4. Reward success: Treats, toys, or voice praise to strengthen learning.
5. 5. Supervise during the first few weeks: Keep sessions short and always positive.

🧠 Why Dogs Escape Boundaries

• 🐿️ Distractions (wildlife, other dogs)
• 😰 Anxiety or separation stress
• 🧬 Breed drive—working and hound breeds may wander
• 🎯 Lack of consistent training or reinforcement

Even with good systems, supervision and backup containment are important.

📊 Pros & Cons Overview

🎯 Final Thoughts

Invisible fences can be helpful—but only when used safely and ethically. Electric shock-based collars pose serious health and behavior risks, and are illegal in Australia. Instead, embrace modern, positive reinforcement tools like the Ask A Vet Premium GPS Health Tracker that guide and protect your dog—without pain.
