Good but the plastic needs to be stronger
Love my system! Installed it on about an acre of hillside land, and it works great! Flash was trained up on it in about 3 days as a 9 month old lab. It was a breeze with lots is flags, treats, and flushing him away from the line. I have to say it was pretty cool to watch the little guy look up and down the line of flags, as if to say "okay I get it, let's party!" The only down side is that mine is three years old and the only issue is the screws holding the battery cover on. Like many of you have experienced the plastic corners chip out and before you know it water from snow and rain seeps in and destroys the collar. Wish there was a neoprene wrap or something to keep is protected better. Not looking forward to spending another $100.


Thank you for sharing your and Flash's experience with the SportDOG In-Ground Fencing system. We highly recommend completing the full training guide, but are glad to hear that your lab was able to be trained to the system so quickly! We are sorry to hear of the trouble you have experienced with the housing of the collar. Please know that this feedback has been passed along and we do value the voice of our customers. If you have any questions or concerns, please give us a call at 1-800-732-0144.

Great fence system! I invented my own collar though.
We purchased the SportDog system over four and a half years ago as a birthday gift for our two yellow labs. This has been the best thing ever! Labs are high energy dogs and need to be able to RUN and not just go on walks. We live in a village next door to an apartment complex and the fence allows us to just let them out the door to go to the bathroom and play. We can work and relax in the yard and they just hang out with us, play, chase sticks & balls, etc.

Over the years they have only gone outside the fence a handful of times even though they are distracted by squirrels, kids & dogs from the apartments next door and more. I highly recommend it.

I have had to replace the collar boxes a couple of times due to my male dog chewing on the female dog's collar and destroying it. This isn't the fault of the product though as there is NOTHING that can stand up to a determined labrador when he wants to chew it up!

We initially had a lot of trouble with one dog (the same one as above) chewing the collar off of our 2nd dog. I would then have to search the yard and woods to try to find it. After replacing the collar a couple of times I finally invented my own by replacing it with some metal chain of the appropriate length under the screw posts on the receiver box so that they could NOT be chewed. I also added clips to the chain so that the collar can be quickly put on and removed as they go in and out of the house all day long (we do not leave the collars on while in the house!). This has worked very well for several years.

You need to commit time to properly train your dog to the fence - two to three times a day for three to six weeks, exactly as described in the instructions! Yes it takes time, but if you do it properly you will be able to trust your furry baby to stay where he belongs. If you move the fence you can quickly retrain.

I highly recommend the SportDog fence system. It works very well and keeps our dogs safe and at home where they belong.

Great system easy to use collar needs improvement
I have had the system for my coonhound for two months now it took some time to get him to stop sprinting past the boundary pbut now he is only on the vibratroy/audible correction my issue is one of the prongs broke off of the collar I think that it would be better if the collar was designed more like the tracking collars where the strap goes around the reciver I'm glad to hear there is a two year warranty.


Thank you for sharing your experience with us, Austin! It is great to hear that your dog has been easy to train to our In-Ground Fence.

Please know that your feedback will be passed on to the appropriate parties and that this system is covered under the 2 year warranty. For troubleshooting and warranty assistance, please give us a call at 1-800-732-0144.
