E-Collar Training Kit for a Medium Dog
Share
Ask three trainers what a first time e-collar owner should buy and you will hear the same model number back. The Mini Educator ET-300 is that default. The rest of this kit is what the ET-300 needs to be useful in week one: a fifteen foot line, a spare biothane strap, a clicker that stays on your finger, and beef liver worth turning around for. Our other kits are indexed on the bundle guides hub.
Where this sits in the process
You have a dog between about twenty five and sixty pounds. It walks reasonably on a leash, it knows its name, and it has been coming when called in the yard for months. What it has never done is come back from something genuinely more interesting than you, at a hundred feet, in a place it has never been. Educator describes the ET-300 as suiting first time e-collar owners and experienced handlers alike, and lists it at half a mile of range. Half a mile is not the point. The point is that you can be specific about timing at a distance where your voice arrives late and your leash does not arrive at all. Our beginner's guide to remote dog training is the long version of the sequence this kit is built for.
If your dog is under twenty pounds the receiver is wrong for the neck, and the small dog kit is the one to read.
Transmitter, long line, spare strap, clicker, liver
The ET-300 transmitter and receiver do the communicating. Educator says this is the model that made the brand its name and describes it as a palm sized transmitter with a hundred adjustable levels of low level, wide pulse stimulation plus boost. Educator also lists tone and vibration modes, a Lock and Set control that stops the level changing by accident, waterproof construction, and the option to expand to two dogs. In practice you will spend two weeks finding the level your dog notices and then never move off it. One detail worth knowing before it arrives: Educator states the system ships with the 5/8 inch Standard Short contact point, and says 163 of the 302 breeds on its own coat chart need something longer than that.
The fifteen foot line teaches. Educator calls it the unsung hero of recall training and says it gives the dog room while you keep a safety net, coming off only when the response is reliable. Every honest e-collar program runs on a line first, because a dog cannot learn what a tap means until you can make the right answer happen.
The spare biothane strap is not a luxury. Educator describes these straps as shrugging off mud, lakes and road trip life, and says 3/4 inch is the standard width for most of its receivers, the ET, ME and 900 series units included. One strap means a creek walk on Saturday leaves you drying a collar on Sunday. Two means you swap and carry on. Educator also notes that straps stretch and the holes wear, which is a quieter cause of inconsistent contact than most people expect.
The FC-100 clicker rides on the hand that is already holding the transmitter. Educator describes it as a finger clicker with a five inch velcro strap that marks the exact moment the dog gets something right. A box clicker ends up in a pocket, and a marker in a pocket is a marker that arrives two seconds late.
Beef liver is the payment. One ingredient, freeze-dried in small batches in Malvern, Pennsylvania, and it ships from us rather than from Educator. It comes in 1.5, 3 and 6 ounce bags; buy the 3 ounce first and find out how fast your dog goes through it before you commit to the large. Pieces come broken into training sizes and the texture is lightweight rather than greasy, which is why it survives a pocket. The rest of the range sits on the freeze-dried dog treats page, and the treats hub groups it by how people actually use it.
One practical note before you order. E-Collar Technologies items are sold and shipped by E-Collar Technologies through Shopify Collective, not made or shipped by Sniff and Shift. That covers four of the five things here: the ET-300, the line, the spare strap and the clicker. Only the liver leaves Malvern, on its own tracking, which usually means the smallest box on the doorstep is the one with the treats in it.
What we deliberately left out
No contact point set. Most starter bundles include one, and it is guesswork until you have seen the collar on your own dog's coat. Educator's own guidance is to match point length to the coat, short for smooth, long for thick fur, so order points after you have looked rather than before. Part the fur at the throat, and if you cannot easily see skin, use the Explore filters or the breed chart to go longer.
No holster either. A belt clip does the same job for less bulk on a dog this size, and it is listed here as an add on if you want one.
Week by week, the first month
Week one: collar on, transmitter off. The dog wears it for a few hours a day so the hardware stops being an event. Fit it high on the neck, two fingers under the strap, and move its position every few hours.
Week two: find the level with the dog on the line and nothing else going on. Work up one step at a time until you see a flicker of attention. Stop there. Pair that level with the recall you already have, and pay every single one with liver.
Weeks three and four: add distance, then add distraction, never both at once. The line stays on the whole time. If a recall fails twice in a row you have made the picture too hard, so go back a step rather than up a level.
What it replaces
A long line by itself, which is where most people start and stall. The line gives you control but no way to be precise about the moment, and a thirty foot rope in a field is a tangle waiting to happen. This kit is the same program with timing added, and it keeps the line where it belongs, as the thing that makes the answer happen rather than the thing you rely on forever.
Questions
Is the ET-300 too much collar for a forty pound dog?
No. The hundred level dial exists so that most dogs work in the bottom fifth of it, and a bigger number on the box does not mean a stronger tap at the level you actually use.
Do I need the clicker if I have the transmitter?
They do different jobs. The clicker marks a correct behavior you are rewarding; the transmitter cues a behavior at distance. Plenty of people run both in the same session with the clicker on the same hand.
How many straps is too many?
Two is the working number for one dog. A third is only worth it if the collar lives in a truck and you keep losing track of which one is clean.
