Neil's Review

"Top quality Dog Containment Fence the Sportdog SDF-100 is suited to larger working breeds due to larger collar and four correction levels.   Comes with 300m of wire compared to all others that only offer 150m, making it a great choice for properties 1/2 acre and above.  Built in lightning surge protection is another bonus! 

SportDog Stubborn Dog Fence SDF-100A

The SportDog Stubborn Dog Fence is best suited to larger stubborn breeds on properties from 1/2 an acre to 100 acres.  The system represents great value as it comes with 300m of wire, unlike all other systems that come with 150m as standard.  The waterproof SDF-R Collar Receiver is made tough, with a buckle up vinyl strap and uses a replaceable 9v battery that will last for 3-6 months with average use.  Additional 150m boundary kits can be added to the system to cover up to 100 acres.

The SportDog receiver collar has four high-level adjustable correction settings.  This may not be suitable for particularly timid/mild temperament dogs. This system is best suited for acreages and larger properties with no colorbond fencing.  Please feel free to call if you are unsure of which fence is best suited to your dog and your existing circumstances.


Suitable for all stubborn dogs over 15 kgs including, but not limited to, the following breeds (adult dog):

  • German Shepherd
  • Kelpie
  • Cattle Dog
  • Labrador
  • Rottweiler
  • Doberman
  • Golden Retriever
  • Ridgeback
  • Maremma
  • Wolfhound
  • Staffy
  • Husky / Malamute
  • Bull Arab
  • Bull Terrier
  • GSP
  • Weimaraner


The SportDog Stubborn Dog Fence is a better value option if considering the PetSafe Stubborn System and adding extra boundary wire, due to the 300m of wire that comes standard with the SportDog system, as well as the more powerful transmitter and better quality collar.  Regardless of breed, if you have colorbond or sheet metal fencing the wire needs to be buried at least 1.5m off the fence due to interference with the radio signal.


The SportDog Stubborn Fence transmitter is plugged into mains power in an area protected from the weather (we recommend a powered shed, garage or laundry for example).  The coated boundary wire is run from the transmitter, around the boundary (in-ground or attached to your existing fencing with cable ties), and returns back to the transmitter to complete the radio signal circuit. The dog wears its SDF-R receiver collar that picks up the radio signal carried along the wire running around your boundary.  The dog receives a warning tone as it approaches the no go zone and if it continues to move towards the boundary it will receive the harmless static correction.

Training is the most important part of setting up an electric dog fence.  Proper training ensures that your dog understands the exact boundary limit and that they must retreat from the fence line when they hear the warning tone. Learn more about training your dog here.
