In short, no.
If your mind immediately conjures up an image of a dog being nearly tasered when going near the boundaries of his wireless fence, we can reassure you that this is absolutely wrong. We are enjoying so many benefits of living in an age of such remarkable technology, so why not share this innovation with our canine companions? Let’s examine one of the most amazing inventions for owners since the leash: the wireless fence!
Giving your dog the gift of doing his job: roaming freely in his own yard
In your dog’s eyes, you are a member of his pack, whether you realize it or not. Whether you want to be, or not. As a member of his pack (hopefully, you have established yourself as the alpha,) he feels it is his job to protect you ALL THE TIME. We know that those 3 a.m. “notifications” that a strange car has driven by are beyond annoying, but it is just your dog earning his keep and letting you know that he is watching out for all of you. He is never “off the clock.”
Given the chance to roam as far and as wide on your property as possible is like giving him a golden ticket to happiness. Dogs with jobs are happier-all puppy trainers know this. Being able to let your canine outside, unattended and off-leash is a gesture that speaks volumes to your pet. It communicates to him that you trust him to do his job, and he will reciprocate with a deeper trust and respect for you. This will manifest itself in better, more appropriate behavior for you and for other people you bring into your home.
Collar Shock Value
Today’s wireless fences are not unlike the first models that were sold back in 1973, the year Richard Peck patented the first one. They have three elements: a transmitter, a collar/receiver, and a wire. However, due to advances in technology and materials engineering, the level of customization you can employ in your system is truly amazing.
With all but the most curious, tenacious, and aggressive dogs, it doesn’t take much to curtail inappropriate behavior and reinforce acceptable behavior. The mild, ticklish sensation emitted to your dog’s collar when he enters into off-limits territory lasts barely moment and is not unpleasant. It is even less painful than the annoying static shock you get when you touch a metal railing in a carpeted store. The “correction,” as it’s called, is simply a mild prompt to redirect your pooch to his approved roaming area. These collars will only emit 0.0003 joules of energy, far less than those infomercial products that claim to whittle your waist. Those “abdominal energizers” emit 0.914 joules (and don’t slim your belly at all!)
The correction level can be tweaked to your own dog’s temperament, and there are no set guidelines based on breed, age, or gender.
Wireless Collar Training Camp
All great wireless fence companies will train your pooch to use the new device. This training is crucial to the success of the system.
Step One- Getting acquainted with the new limits
This first step will familiarize your pup with the boundary flags and the special warning tone that sounds when they approach them.
In this step, there is no “correction,” only praise when he steps back from the boundary. The correction mode can be introduced once your puppy learns to keep some distance from the new perimeter.
Prior to this training, set aside ample time to play. Add treats to help maintain his energy for the training session, and set a positive tone.
Place a leash on your pooch, and let him lead you around the yard. He will hear a warning tone if he approaches the flags. Say “no” in a commanding tone and lead him away. Once he starts backing away on his own, praise and treat him. 
Step Two-Enter the correction
In this step, the consequence of a static correction is introduced. You already taught him to back away at the sound of the warning tone. Now, using the lowest setting, a small correction will happen if he broaches the boundary line. His response should be to look around for the source and then move away quickly.
Remember to reward and praise your canine when he behaves as he should around the boundary flags, by backing away from them. Reinforce this good behavior frequently.
Step Three-Hey, look, a squirrel! Or, introducing distractions
What tempts your dog the most? A toy, another dog, the mailman? Do some training when you are able to have a distraction on the other side of the boundary. Throw his favorite toy over the line, or have a friend walk their canine near the perimeter.
Praise and treat if he doesn’t cross the line. If he does give into temptation and gets too close, simply say “no!’ like you did in Step One, and pull him away quickly.
Step Four- The sweet smell of freedom
Now he is ready for some off-leash fun. Your aim is to slowly increase his off-leash time in the yard, eventually letting him roam unsupervised.
First, bring him to the yard and remove his leash. Play with him for a while, then leave him alone for a bit (while you remain in the yard.) Praise and treat him if he keeps himself in the boundary zone for those few minutes.
You want to have these short sessions fairly regularly at first, and slowly increase his time off the leash.
Should your fur baby still break his boundaries and test the limits, return to Step Two and work your way back up to Step Four.
Wireless fence equals happy pup equals peaceful owner
Giving your dog the gift of his freedom via a wireless fence is one of the most caring things you can do for him. Chuck any fears you may have had about these amazing devices, and seriously consider installing one. Your dog will thank you (in his own, slobbery way!)
