Are invisible fences good for large dogs?

Invisible fences, also known as underground fences or electronic fences, are a controversial topic among dog owners and trainers when it comes to their use for large breed dogs. An invisible fence system consists of a wire buried around the perimeter of a yard and a receiver collar worn by the dog. When the dog approaches the boundary, the collar gives a warning beep, and if they continue forward, delivers a mild static shock. The idea is to train dogs to stay within the boundary to keep them safely contained. However, many argue that invisible fences are ineffective and potentially dangerous for large dogs due to their size and strength. This article will examine the key considerations around invisible fences for large dogs.

Do invisible fences work for containing large dogs?

For many large dog breeds, standard underground fences may not be sufficient to keep them contained. Large dogs can build up a high level of tolerance and resilience to the static shock over time. Additionally, large dogs can be capable of breaking through the shock barrier due to their sheer size, strength and determination, especially if they are highly motivated to escape or chase after something on the other side of the boundary.

According to dog trainer Cesar Milan, invisible fences are often unreliable for dogs over 50 lbs. Larger dogs are also capable of knocking loose the wiring or damaging the system through digging. Milan recommends traditional fencing as a more secure option for big dogs. Other trainers warn that some large dogs can even learn to “run through” the shock barrier if their desire to escape is strong enough.

However, some owners have success using invisible fences with their large dogs when the system is properly introduced and the dogs are sufficiently trained. Using flags to clearly mark the boundary during initial training can help larger dogs respect the fence line. Setting the static shock to an adequate intensity level for the dog’s size may make the barrier more aversive. Consistency in training and monitoring the dog’s response to the barrier is also important.

Are there risks to using invisible fences for large dogs?

While invisible fences may keep many dogs contained, critics argue they do little to keep other animals or people out of a yard. Large dogs who feel territorial and protective of their space can potentially be dangerous if an invisible barrier is all that separates them from perceived intruders. In these scenarios, a physical fence provides a better safety barrier.

There are also risks if the system fails. If the power goes out, the fence shuts off allowing the dog to roam freely. Battery malfunctions in the collar can also turn off the warning correction. Battery life usually ranges from 3-6 months so frequent monitoring and replacement is required.

Additionally, invisible fences do nothing to prevent other unrestrained animals from entering the yard and causing trouble. And if a fight breaks out between your large dog and another loose animal, there is no physical barrier to separate them.

Does the shock from an invisible fence cause stress in large dogs?

While manufacturers claim the shock from invisible fences is harmless, some animal behaviorists argue it can cause undue stress, anxiety and fear – especially among certain sensitive breeds. The shock sensation is likely more intense for dogs with thicker coats like heavy fur or skin. Large dogs may be more easily spooked or provoked to aggression by the surprise of the correction.

The invisible boundary is marked by such an unpleasant consequence that many dogs become fearful of getting too close to the border. As a result, they may limit their movements to avoid the shock zone. This can suppress a dog’s natural behavior and desire to patrol, run or explore their surroundings.

Are some large breeds unsuitable for invisible fencing?

Certain large, powerful and independent breeds are poorly suited for containment using invisible fences according to trainers. These include huskies, malamutes, great danes, wolf hybrids, and livestock guardian breeds like Anatolian shepherds. Their high prey drive, tolerance for pain, or stubborn nature makes them more likely to bolt through the barrier. Herding breeds like border collies can become neurotically fixated on the boundary line.

Sighthounds like greyhounds have such a strong instinct to run when they spot potential prey that they will blast through the shock without hesitation. Their thin coats also make them extra sensitive to the correction. Other breeds prone to aggression like chows may become territorial and lash out against animals or people approaching the fence boundary.

What age should large dogs be introduced to invisible fencing?

Manufacturers typically recommend waiting until a puppy is 6 months old before introducing invisible fence training, but some trainers argue large breed puppies should be closer to 10-12 months old. Puppies under a year haven’t reached their full size and strength and may not yet respect the fence, increasing escape risk. The static shock may also be unduly frightening on a young pup.

Starting too early can promote fence running/testing behaviors that are hard to break later on. Wait until your large pup is mature enough to begin training them on the invisible fence system. Work with a professional trainer for best practices customized to your dog’s breed traits and temperament.

Are there alternatives to consider?

Instead of an invisible fence, some alternatives for safely containing large dogs include:

• Traditional fencing like wood, chain link or privacy fences installed at adequate height (6 feet or higher)
• Welded wire fences with a rolled top edge to prevent climbing/escapes
• Double fencing with an inner electronic fence and a perimeter physical fence for backup
• A wireless containment system that covers a circular area allowing the dog more freedom than a fixed perimeter wire

You can also consider long lead tethers or outdoor kennel runs as safe spaces for your dog to enjoy the fresh air without risk of escape.

Tips for effective invisible fencing for large dogs

If you do opt to use an invisible fence with your big dog, some tips include:

• Choose an appropriate containment system designed for your dog’s size (5 acres or more)
• Use boundary flags and monitors during initial training
• Keep their static correction level appropriately high
• Acclimate them slowly to avoid fear
• Reinforce training until they show clear understanding
• Do not leave your large dog unsupervised until trained
• Have a back-up plan for temporary system failures
• Monitor for signs of stress like pacing the fence line
• Be prepared to transition to traditional fencing if ineffective

Conclusion

Invisible fences can work for some large dogs but carry more risks compared to smaller breeds. They require extensive training and diligent monitoring to keep a powerful, strong-willed dog contained. Even properly installed and introduced, electronic fences may still fail to overcome high prey drive or determination to escape in certain large dogs. For highest security, traditional solid fencing is typically the safest option for big dogs. But with caution and patience, invisible systems offer a containment alternative for owners willing to put in the effort to train their large dogs.
