PetSafe Boundary Wire

View on Amazon

The PetSafe Boundary Wire is an excellent option for pet owners seeking a versatile dog fence wire that offers multiple fence configurations.

With the ability to extend an existing fence up to 500 feet or be buried to create an invisible fence, this wire provides plenty of options for pet containment.

The wire works seamlessly with in-ground fence kits from PetSafe, Guardian, and Innotek and is also available in 16-gauge and 18-gauge gauges.

One drawback is that the spool is made of cardboard, which may be damaged when unspooling the wire. However, we believe that this is one of the best dog fence wires on the market this year.

When using this product, it is recommended to use gel-filled splice capsules and wire connectors (RFA-366) for optimal performance.

In summary, the SportDOG Wire is an excellent investment for pet owners seeking to expand their existing in-ground fence system and provide their dogs with more space to roam.

One downside of this product is its higher cost compared to other options on the market. Additionally, the wire may be prone to tangling, making it challenging to unwind 500 feet of it.

Buyer's Guide

There are numerous factors to consider while deciding between various types of dog fence wire

1. Wire Gauge

Electric dog fence wires come in standard sizes of 20 gauge, 18 gauge, 16 gauge, and 14 gauge. Thinner wires, such as 20-gauge, are often cheaper and commonly used in do-it-yourself fence kits.

However, professionally installed systems use thicker wires, such as 16 gauge or 14 gauge, which may be more expensive but offer better durability and signal transmission.

2. Durability

Because dog fence wires are exposed to the elements, it is important to choose a wire with high endurance. Thinner gauges may offer better durability, and a plastic or vinyl coating can provide additional protection.

For example, a polyethylene coating can offer a watertight layer of protection for wires buried underground.

3. Superior Quality

The quality of the spool is also important, as a low-quality spool can disintegrate during the unwinding process. High-quality plastic or metal spools can make the unwinding process easier and prevent wire damage.

4. Signal Transmission

To ensure consistent signals and proper electrical transmission, it is important to use the same gauge of wire when adding to an existing dog fence system.

In larger properties, thicker gauge wire may be beneficial in extending the signal’s range.

5. Stranded vs. Solid Core Wire

Copper wire for dog fences is available as stranded or solid-core wire. Stranded wire is more flexible and easier to unwind, but it may deteriorate more quickly due to rust.

Solid-core wire is less flexible but more corrosion-resistant and suitable for above-ground fences. While solid-core wire may be more expensive initially, it offers better longevity and durability.

In summary, choosing the right dog fence wire involves considering factors such as wire gauge, signal transmission, durability, spool quality, and stranded vs. solid-core wire.

These factors can help ensure the optimal performance and longevity of your dog fence system.

What is a dog's Underground Fence Wire?

Underground dog fence wire is a crucial component of an invisible fence system that keeps your pet safe and contained within predetermined boundaries.

These wires are designed to be submerged underground and feature a professional-quality polyethylene coating that protects against water exposure and ultraviolet radiation.

It is essential to choose burial-grade wire when purchasing fence wire to ensure its durability and dependability. This wire is included in a setup for an invisible fence that also includes transmitters and a dog harness.

When your pet approaches a boundary wire, the wire transmits a signal to the transmitter, which then sends a radio signal to the dog’s collar.

For efficient dog training, flagged fence wires are highly recommended. During training, it is not necessary to position the flags precisely above the exact electrical location.

Instead, scattering them along the fence’s perimeter or in locations such as the pool for two weeks is sufficient for your pet to comprehend the boundaries.

There are numerous ways to install an underground wire fence. A common technique is to conceal the wire along the yard’s perimeter. However, to enhance signal strength, it is essential to bury the wire at the prescribed depth, which is typically at least 3 inches.

Depending on your requirements and the extent of your yard, you can bury the wire in various ways. For instance, if you primarily keep your pet in the backyard, wiring the backyard alone may suffice.

Another option is to separate the front and back barriers with wire, leaving space along the boundary between the front and backyard.

Choosing the appropriate burial-grade wire for your underground dog fence system is crucial for ensuring its durability and dependability.

With proper installation and training, an in-ground wire fence can provide a secure and effective method for containing your pet within predetermined boundaries.

FAQs

1. Is there anything special about dog fence wire?

Yes, professional-grade dog fence wire offers long-term reliability, making it a worthwhile investment for pet owners.

Upgraded wire is designed to withstand freezing and thawing conditions, ground expansion, exposure to water and chemicals, and general wear and tear.

This means it can provide better performance and durability than standard kit wire, making it a smart choice for those looking for a reliable and long-lasting dog fence solution.

2. What is the strongest fencing for dogs?

Metal fencing is the strongest option for dogs, as it can withstand extreme weather conditions and is difficult for dogs to chew through or jump over. Vinyl and wood fencing are also durable choices for dog fences.

3. Is solid or stranded wire better for dog fence?

Solid-core wire is the better choice for dog fences, as it is easier to work with and more durable than stranded wire. However, stranded wire can still be used if solid-core wire is not available.

4. How deep should wire be for extreme dog fence?

It is recommended to bury the dog fence wire no deeper than 2 feet. If you need to bury the wire deeper, make sure the dog fence transmitter can be adjusted to compensate for the depth.

5. How long does dog fence wire last?

The life expectancy of dog fence wire depends on the type of wire used. Direct burial grade wire, such as the Invisible Fence® Brand boundary wire, can last up to 27 years if left undisturbed in the ground.

6. Is 20 gauge wire good enough for dog fence?

While 20-gauge wire is cheaper and lighter, it is not as durable as thicker wire. For most dog fence installations, it is recommended to upgrade to heavy-duty wire for better resilience and longevity.

7. What fence can dogs not climb?

For dogs that cannot clear a 6-foot jump, estate fences, block wall fences, wood privacy fences with the “good side” facing in, and vinyl fences are all options for dog containment.

These fences do not provide horizontal supports for dogs to climb on, making it difficult for them to escape.
