  • A pet containment system that functions mainly with a transmitter/pager and a collar receiver
  • This is an in ground fence which requires you to bury boundary wire for the perimeter of the system
  • You get 500 feet of boundary wire in the kit which will give you under an acre total coverage, but with additional wire, you can cover up to 40 acres with the strength of the pager/transmitter
  • The collar receiver is for dogs as small as 15 lbs
  • The collar receiver delivers low to medium power static stimulation to your dog for correction when they enter the correction zone
  • The collar has a static stimulation level selection dial
  • There’s also a vibration only training mode
  • The collar receiver is waterproof
  • Has 2 hour rapid charge batteries
  • There’s a wire breakage light and tone on the pager
  • The system comes with boundary training flags
  • The transmitter/pager has a field width adjustment knob, and a function selection switch
  • The transmitter is wall mounted and should be near a power outlet
  • Dogtra is a fairly well established dog and pet brand, so customer service should be OK
  • You can buy more collars to add more dogs to the system


  • Like any in ground dog fence, you’ll need to take a few days to plan out, dig and lay the in ground fence wires.
  • There’s no tone-only training mode
  • There may be some areas of your yard or house, particularly with metal, that may block the signal, or trigger the collars when they aren’t suppose to. Although, you should be able to contact Dogtra to figure the solution out
  • It’s standard across most dog fences, but a 1 year warranty seems short. 2 or 3 years would be better.


  • For the price, this in ground system is actually pretty good. Dogtra is a reliable brand, so there shouldn’t be too much concern about the quality and customer service. The rechargeable collar batteries are a big plus. SportDOG, eXtreme and PetSafe are probably the only other brands that make dog fences of similar reliability. Consider this one if you want a cheaper dog fence with all the basic features and a few advanced ones thrown in


Dogtra E-Fence EF-3500: Buyer’s Guide

What Is The Dogtra E-Fence EF-3500 Designed For?

The EF-3500 is intended to keep dogs larger than 15lbs within an area that 500 feet of wire can enclose, or up to 40 acres if you buy more boundary wire.

It has both stimulation, and vibration training modes.


How Does The Dogtra E-Fence EF-3500 Work?

Dogtra give you a set up and operation/training manual and guide which you should follow. But, as a general guide:

  • You plan out where the fence will go, and the transmitter (you need to have a power source nearby)
  • You lay out the wire above ground and test the system and collars are working
  • You dig the wire trenches and lay the wire and backfill
  • You set the static level on the collar, or set the system to vibration only
  • You also make the necessary setting modifications on the transmitter
  • You put in the training flags above ground so your dog can see where the boundary is and put the collar/s on your dog/s
  • Depending on the mode you set the system to, the collar will respond differently to the warning and correction zones in different locations
  • The training period should be roughly 2 weeks for your dog to learn where the boundary is
  • Once your dog learns where the boundary is, some people choose to remove the collar until or if re-training is required

Some Safety Considerations For Using An Electric Dog Fence

Safety is extremely important with an dog fence.

Always always get your vet’s advice or the advice of an animal health and/or training expert – nothing is a substitute for professional advice.

Some general safety guidelines for using a dog fence humanely might be:

  • Buy from a reputable company who put proper use of the dog fence and the safety of the dog as a priority 
  • Read and follow the operating guide, instruction/safety manual and training guide that comes with the dog fence system from the manufacturer for operation and safety instructions and guidelines
  • Pay attention to any warnings issued by the manufacturer
  • Monitor your dog’s response both mentally and physically to using a dog fence. Take the collar off immediately and discontinue use of the system if you notice any negative implications or reactions

A good dog fence that uses static stimulation should simply stimulate the muscle (to the point of reflex) to get the dog’s attention, but should not cause pain (it might be slightly annoying for the dog to act as a small deterrent – but shouldn’t cause pain or harm). It certainly shouldn’t cause a ‘sharp pain’ to the muscle or body. 

To get a safe stimulation level – you can always start from the lowest stimulation level, and work your way up to a level that gets the dog’s attention (such as changing body language when a stimulation, vibration or tone is administered) without any visible sign of pain or harm (such as yelping, or showing signs of stress).

A good dog fence company should give you all the necessary safety, use and training instructions, and should have a dedicated customer service line to help when you being using the fence system.

The static function does not need to be used either – tone and vibrate training modes can be used instead.

Some owners like to use their dog fence system as a temporary training tool i.e. once their dog/s have learnt the boundaries and are properly training to stay in the yard, they turn the fence off or remove it.

If the dog starts going outside the boundaries again, they use the fence again to re-train their dog.

As a safety precaution for humans as well – make sure to get a qualified company to do an underground utility search and get these utilities marked before doing any digging.
