Best Invisible Dog Fence 2021 Reviews [Top 2]

Thanks to advances in technology, it is becoming easier to get the best invisible fence for dogs. However, although the dosage of the work is reduced, certain characteristics have to be respected and taken into account with respect to others.

In that sense, and to begin with, it is necessary to make clear that the sophisticated systems of invisible fences have a precise objective and to delimit the outer areas where the dog can travel without the need to include other physical barriers.

Ideal for entering or leaving the property by car without the animal escaping, preventing it from moving away from the perimeter or simply keeping an eye on it, these dog safety systems protect and allow the pet to be educated, as well as avoiding situations of risk.

In almost all the presentations of the invisible fences for large and small dogs, the team is armed with a receiver collar and a fiber or cable that delimits the area to be fenced, even where the dog can walk freely.

However, when the animal approaches the area where the cable is buried, the collar emits an alert sound that warns the pet, ordering him not to approach. If it persists in its movement, the collar emits some impulse – call it discharge or buzz – which forces it to retreat. Before this strip and shrinks between the animal and the fence, the dog will learn the limits of its territory.

Although many owners oppose these fences because they are considered harmful to their furry friends, it has been proven repeatedly that the invisible extension of the cable is totally harmless: it does not cause physical discomfort to the dog that wears the collar or to someone who touches the cable.

This is because the fence works with a frequency transmitter that guarantees the safety of the whole family.

One of the great advantages of security systems is their ease of installation. The cable can be molded in the desired ways and forms, as well as it can be buried to prevent it from getting in the way of sight or being discovered by the dog. It also allows the formation of transit zones that allow the animal to circulate freely.

Regarding the models, each brand presents its own versions with similar characteristics, but not the same. Some fences receive signals of 400 meters, others of 1000 meters, while the range of action is adjustable. Also, if the areas to delimit exceed the length of the cable, you can always purchase more from any vendor that sells them.

The fence models for dogs also share a particularity: they evaluate the weight and based on this they create their versions. For example, about 400 meters is ideal for dogs whose weight does not exceed 25 kilos, while longer extensions are useful for larger pets, difficult to train.

Another issue that is equated in hidden fence systems is stimulation levels. Each provider offers them depending on the structure of the dogs, resulting in an option that adapts the hum or discharges from the weakest to the most powerful.

In short, the complete design of an invisible fence will satisfy even the most demanding, especially if it includes such wonderful qualities as load reminders, indicators, and operating manuals and safety settings.

We pick these 2 invisible dog fences for small and large yards in 2021 and explain all their features you pick which your favorite ones.

1) PetSafe Wireless Dog Containment System

PetSafe Wireless Dog Containment System

As a pet containment system, this PetSafe product is an innovative concept that mixes simplicity and safety.

Its use is quite easy. To activate it, the first thing to do is connect the transmitter, which emits a radio signal of 17.5-kilohertz around the construction. This signal is connected with a collar that is placed on the pet and sends the signal.

While the dog is protected by these signals, he can walk freely on all surfaces connected to the fence. If he tried to cross the boundaries, he would receive an alarm signal that is reflected in his collar like a beep.

Consciously, the animal learns that it is his warning to return, but when it comes to very stubborn breeds, he is likely to want to move forward.

If this occurs, the PetSafe Wireless Dog Containment System emits a static current that does not harm the animal’s welfare; rather, it teaches you to define what your limits are.

This action is performed with the cable that starts at the frequency transmitter; progressively increasing its length and adapting to different shapes according to the design of the homes. In that same sense, these fences can be buried so as not to hinder the aesthetics or practicality of the garden.

Once the decision of how and where to install the fence is made, it is necessary to load the collar and hang it on the dog’s neck. This is an educational belt that emits discharge or humming once the animal approaches the areas where the cable extends.

Under normal conditions, the collar should emit a slight beep that tells the dog what its limits are. If the animal insists, the buzzing occurs with the intensity that has been determined. Usually, necklaces handle a range of levels from 1 to 5.

Note: it is not recommended to use the most powerful levels in small pets. Call all those weighing less than 20 kilos small.

Some dog fences allow you to expand your coverage area, through compatible cables, or pennants that help with the delimitation. Most invisible fences work according to the same installation system, but one cannot deny that some are easier than others.

Why do you need the best invisible fence for large/small dogs?

My dog ​​runs through the invisible fence, how do you control it?

As mentioned above, invisible fences work connected to a central unit that emits Hertzian waves or, as in most cases, they work with a cable.

However, there are stubborn dogs that give more work in training and learning, and one of the behaviors can be related to the transfer of the barrier regardless of stimulation.
