How to Select an Invisible Dog Fence?

Thickness and weight can determine the effectiveness of the shock and obstinacy ensures how much your dog is capable to adapt with given instructions.

Things to Consider Before Buying an Invisible Dog Fence
Now it is time to consider some special things before purchasing a wireless fence. To get the highest output you should think about the following things:
The Capacity of the Coverage Area
Boundary size is the major concern for choosing an invisible fence collar for dogs. It only has the transmitter to indicate when a dog crosses the limit of the area. A powerful fence transmitter can cover more than 25 acres of the area where a normal fence has the capacity to cover only 1 acre.
Before purchasing consider the area where it works best in. If your courtyard is odd-shaped then the dog fence may not able to reach every inch of the zone where your dog lives in. Some fence can’t pass signals through structured material like metal or wood.
If there are lots of wooded area in your home with a circular radius, the dog fence system limits the transmitter to reach each point. You should sincere about the installation process and avoid the place where other electrical devices are installed.
It is important to select the right place for dog fence installation from where the transmitter can cover the total area in the range. Electric dog fence installation is not quite tough and you don’t need to be an expert to access this. Just open out the transmitter from the box which you have newly bought and set up on your laptop or computer.
It takes less than one hour to install and run properly. You can also move this transmitter with you, and can set in another place to cover a new range of area. You should also consider the temperature and it should not too high or below the freezing point.
Number of Dogs Allowed
If you have more than one dog, please consider the accommodation area before purchasing the invisible fence. One transmitter can accommodate a minimum of three dogs simultaneously. The receiver collars allowed the maximum number of dogs you programmed into the transmitter.
There are some invisible fence brands allow only one receiver collar for each transmitter, but some brands can perform for more. So, consider this issue seriously if you are the owner of multiple dogs and they live together. It would be easier to install and works faster if activates on only one dog.
Longevity or Warranty
Most of the brands offer a 1-year warranty on every in-ground dog fence. When a brand provides a warranty period they take the responsibility to better care of their users. During the warranty period, manufacturers are compelled to replace the damaged product and as a pet owner, you should choose a dog fence brand which has an adequate warranty period.
You should not use a static correction level on your puppy because it is too intense for them. You need stronger correction levels to control large dog breeds otherwise, dogs may cross the fence boundary. Usually, the correction level depends on your dog’s normal behavior and pain tolerance capacity.
Some electric dog fence brand generates “beeps” when set as the tone-only mode. This feature provides warning rather than shock. It is also useful for dogs are hearing impaired. In this case, if your dog is sensitive to physical pain, then a beep tone feature may be effective to warn from away. So, before purchasing a wireless dog fence you should study the number of correction levels which the receiver collar allows.
The receiver battery is another vital factor which you should consider before buying the fence. The lasting power of the receiver collar’s battery depends on the brand and usage limit. Normally, these batteries last for a couple months when used carefully.
The receiver collars have both rechargeable and replaceable batteries. If you have rechargeable batteries, you don’t need to keep a lot of batteries in stock but for replaceable batteries, you should aware of the voltage power to buy further time.
If the dog is too much playful and likes to enjoy outdoor activities, you should collect the dog collar which has the durable transmitter. Some collars contain additional control options with on/off switch.
It offers a safety timeout option to prevent your dog from receiving too many electric shocks. During the training period, you should observe the whole area of wireless electric fence system to guide your dog properly.
The range of area is another vital aspect of the invisible dog fence. Allowing a large training area should be the main feature for these dog fences. There are different shapes and sizes of an invisible fence. To get the maximum output, you need to set up the dog fence properly and manage the invisible boundary area of the fence.
So, before purchasing a dog fence you should define the boundary area. Then it will be easier to sort out the appropriate wireless fence to keep your dog safe and secure.
