About SportDOG

Dog Training Gear for Every Season

It’s important that your dog’s gear is built to withstand the elements you face in the field. That’s why nothing from SportDOG gets into your hands without rigid testing. Whether you and your dog are doing daily water training in summer or breaking through winter lake ice for long retrievals, SportDOG gear can handle it.

How Do the SportDOG Models Differ?

Most SportDOG e-collars are waterproof and rechargeable and feature tone, vibe and static stim settings. The big differences between the models are collar distance range, number of dogs one remote can talk to, and remote type. Choose from remotes with features like OLED display or a tactile dial for no-look operation.

Battery doesn’t last long

Ok battery only last one day at most and is not very heavy duty so dogs can chew up collar very easy. Shock doesn’t seem very strong either.

Replacement for SportDog Collar

It’s working great. My old “receiver” collar was dying and it wasn’t working to full strength. I guess there is about a 7-8 year service life. Anyway - it’s good to have Finn (10 year old chocolate lab) at his full obedience level.

Love but don't last long for the money.

We absolutely love our sport dog e-collars. My pups wear them on hikes, swims, and in the yard. However, we are now on our third set in 5 years. They are quite pricey to not last more than 1-2 years - in my opinion. My pups swim in them but they don't wear them more than 2 hours per day. This one never had a strong beep, and now is failing to work. Again, I love the functions of this collar - especially when having multiple dogs, as well as being able to change the band. I just wish they lasted longer.

We bought this additional collar to add on to our other dog control collar. When adding a 2nd collar to a single controller, the buttons are then assigned to a specific collar. That is nice, you don't have to worry about switching a button or dial to send a signal to the correct dog. the only issue is having to remember which button is for which collar.
