LOVE the fence system but the Collar Transmitter design needs a major update!
I have had my In ground fence system since 2014 and LOVE it! But the collar transmitters leave a lot to be desired. I am on my third or fourth replacement of the transmitters due to the casings breaking at the screws, water getting in and causing it not to work; or the prongs breaking off from the casing. Sport Dog customer support is FANTASTIC! And have always replaced my collars for me when I contact them. It is disappointing though to keep having to replace them and worry that they may not be working on my dogs when I am not home. I lost 2 young dogs to being hit by a car at the same time; thus resulted in my purchase of the in-ground fence system. I don't want that accident to happen again due to the collar not working properly. My dogs play together and rough house in a snowy climate, thus the waterproof feature is important. I also have the GPS tracking hunting collars and have never had issues with those at all. If the engineering and design team could build a collar similar to those ones for the In Ground Fence system, I think it would sustain dog behavior and durability ALOT BETTER! SportDog has fantastic customer service and I recommend the products to everyone I know, but do have to mention the problems with the collar transmitters. Thank you for standing behind the product with the replacements, but I hope a new design is coming soon!

Love the system, have issues with the collar
The invisible fence has been fantastic for our dog, however, the collar needs to be replaced. We already purchased a new strap as our original was falling apart. Unfortunately, screws fell out from the transmitter. We put them back in a number of times, but the last time they fell out, the battery was dangling and one of the wires broke. Unfortunately, we need to purchase a whole new collar system.

​SportDOG Response:

We're sorry to hear about the issues you've run into with the receiver collar, Beth! The collar carries a two-year manufacturer's warranty which would almost certainly cover this problem you're experiencing. Please give us a call at the number 1-800-275-6797 for assistance.

Great system, collars don't last.
First and foremost I love this system and the fence works great, I would give the fence 10 stars! But out of 6 collars I am down to 3 working collars in a year and half one of which I have replaced. The casings break, loose screws, contacts break off and one just quit working. I am not looking forward to either replacing collars every year or so or only being able to let 3 dogs out at a time which will most likely be the case at $100 a collar. I have recommended this system to others with the caution of collar care. Being a "Sport" dog company I would think these would be a bit more indestructible. I understand that things don't last forever, but a golden retriever chewing on sticks or chasing a ball, it should last longer.
Thank you for your company and encourage people to buy this product, even with the flaw it is worth it and your customer care is great too, just hope your design team looks into this.
