Bought brand new and I can’t even hear the beep to train my dog to jerk him back with a leash beep is way too low

​SportDOG Response:

We're sorry to hear that it is difficult to hear the warning tone from the receiver collar, Kevin! Because the sound of the warning is set to a frequency and volume both comfortable and safe for your dog, some people may have trouble hearing the warning from a distance or will hear it as a low clicking or ticking sound rather than a loud beep. During the training process, since the static stimulation is not yet being used, it may be a good idea to temporarily fit the receiver collar so that it is on the top of your dog's neck rather than underneath, which may make it easier to hear the tone. After the initial training process, you can then fit the collar normally.

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.
