Electric Dog Fences: Do They Work?

How Does an Electric Fence Work? Three Truths That Dog Owners Must Know

Every time I walk my dog ​​and see my neighbor’s Border Collie running in circles in the yard, I wonder how that “invisible” wire works. Later, I disassembled the machine and found that the principle is very simple:

1. Signal base station: transmits signals like a router (wireless model) or connects to buried wires (wired model)

2. Smart collar: When the dog approaches the boundary, it will first “beep” to warn, and then release slight static electricity (adjustable intensity)

3. Visual marking: In the initial training, you need to insert a small flag to help the dog remember where the “warning line” is

For example, the SportDOG underground model I use can customize irregular boundary lines, which is especially suitable for my garden with a slope. But novices are recommended to start with the PetSafe wireless model. It is really easy to not have to dig the ground!

When I was a volunteer at a pet show, I saw too many tragedies of buying the wrong fence. Remember these tips:

Choose a mode according to the physical condition

• Timid poodles: Choose a dog fence collar electric with vibration + sound warning

• Erhachi “jailbreak expert”: Be sure to use the best dog electric fence with 10 levels of adjustable static electricity

The battery must be durable

Last winter, I tried a certain brand of collar, and the temperature was low and it ran out of power. The dog almost ran away. Now I only dare to buy the top-rated electric dog fence with IP67 waterproof + 20-day battery life

Terrain adaptability

• Villa compound: The best electric dog fence with honest buried wires, the signal is as stable as that of an old dog

• Tenant: Recommend portable electric dog fences wireless that can be taken away when moving

After-sales service must be reliable

The key is to see if there is training guidance! The Extreme Dog Fence I bought comes with a 30-minute video course, which is 10 times more effective than reading the manual

Training diary: My Labrador learned to follow the rules in 3 weeks

1. Day1-3: Take the dog to recognize the small flag, shout “pay attention to the boundary” every time it approaches, and give snacks as a reward

2. Day4-7: Deliberately lead it to the boundary, and immediately use toys to divert its attention when the collar vibrates

3. Day8-14: Untie the leash for 10 minutes every day, and hide behind the curtains to observe the reaction

4. Day 15-21: Remove 80% of the flags, and occasionally deliberately open the door to test (must be present!)

Blood and tears lesson: Never train on thundering days! Once a heavy rain caused signal confusion, and the dog was misfired and dared not go out for three days…

Don’t buy an electric fence in these situations

⚠️ The dog has separation anxiety (maybe stress)

⚠️ There are stray cats/squirrels nearby (chasing instinct is hard to control)

⚠️ There are multiple dogs at home (easy to stimulate each other and cross the line)

Last year, when I helped a pet school do an evaluation, I found that the success rate for working dogs such as shepherds and German shepherds was as high as 92%, but only 67% for stubborn dogs such as pugs

You can buy with confidence:

• If you have a “perpetual motion machine” at home, choose the Fi series (GPS tracking + motion monitoring)

• For an art garden, choose the Havahart wireless model (completely invisible and traceless)

IQ tax warning:

• A certain Internet celebrity magnetic fence (large dogs will move when they hit it)

• Super low-priced miscellaneous brands (the signal floats in the rain, causing me to look for the dog all over the community)

Written at the end: This is not a shackle, but a two-way trust

I have used electric fences for 3 years. The most touching thing is that once I forgot to charge it, my furry child stopped outside the usual boundary line and wagged his tail. They are smarter than we think. The key is to use the right method. Now every morning, I watch the dog rolling in the sun, and finally, I don’t have to worry about guarding the fence gate anymore-this is probably the most gentle gift that technology has given to shit shovelers.

Tips: Remember to trim the hair at the contact point of the collar every month, and the signal will be more sensitive!
