Performance notes

The receiver runs up to 100 safe tapping stimulation levels and includes a night light for locating your dog after dark, both waterproof and rechargeable so there's no disposable battery to manage. The biothane strap and buckle closure are built to hold up across weather and repeated use, and the two sets of contact points let you match the fit to your dog's coat length.

What buyers say

With 6,600 reviews at a 4.6 star average and around 300 units bought last month, the ET-300 has a large, steady base of repeat buyers, consistent with an established model rather than a new or niche release.

Frequently asked questions

How far does the ET-300's remote reach?

The manufacturer lists a 1/2 mile range, which covers most yards, parks, and open training areas. That range gives you plenty of room for off-leash recall practice without losing the connection.

Is the ET-300 suitable for a large breed dog?

It's recommended for medium and small dogs rather than large breeds. If you have a bigger dog, look at a model in this lineup with a Large breed size recommendation instead.

Does it work in wet weather?

Yes, both the transmitter and receiver collar are waterproof, and the receiver is rechargeable rather than relying on disposable batteries. That combination makes it practical for training in rain or around water.
