Haz says: This is the SMALLEST E Collar I have ever seen. It beets all other brands in terms of size. This will legitimately fit an 6-12 lb dog no problem. Much smaller then the micro educator. If you have a little dog or are looking for a very small e collar this is it!

The Dogtra iQ MINI delivers all the essential features of a remote trainer in a petite form specific for smaller dogs. It offers the lightest and smallest receiver, weighing at 1.3 ounces, with ergonomically designed plastic contact points, making it ideal for dogs as small as 7 pounds.
