The ME-300 Micro Educator remote e-collar pairs the popular ET-300 Mini Transmitter with the newly designed RX-070 Micro Receiver, ideal for small dogs. The RX-070 is a smaller, lighter version of the RX-090 Mini Educator Receiver—approximately 20% smaller, lighter, and offering 20% less stimulation. To better suit small dogs, the contact points are positioned 20% closer together, and the collar can be rotated 90 degrees on the strap, allowing for a “fore and aft” placement instead of traditional side-by-side contact points. While it remains suitable for dogs weighing 5 lbs and up like the ET-300, the updated design provides enhanced fitting options for very small dogs.
