E-Collar Training Kit for a Large or Stubborn Dog
Share
Most complaints about remote collars on big dogs trace back to two of the cheapest parts in the box: a strap that is too narrow for the receiver and contact points that never reach skin. This kit puts the right strap next to The Boss ET-800 from the start, adds the fifteen foot line every honest program runs on, and pays the dog in beef heart. Our other kits are indexed on the bundle guides hub.
Dogs this was assembled for
Seventy pounds and up, or a dog of any size that has learned to work through a smaller unit. Educator is blunt about where the ET-800 belongs. The company describes it as built for large, powerful or determined dogs and for handlers working at distances that get serious. Educator is equally blunt about the other direction, and says that under about forty pounds, or for an owner who rarely leaves the park, the Mini Educator is the better fit. Take that seriously. Buying up a model because the dog is difficult usually means the fit is wrong rather than the output.
The behavior side of this is a separate job from the hardware. Our recall training guide covers the sequence, and nothing on this page replaces it.
The ET-800, the one inch strap and the line
The ET-800 is the system. Educator says it delivers a full one mile range and stronger output than the smaller units, with the same low level adjustable communication the brand is known for. The feature list Educator publishes runs to a hundred adjustable low level steps, tone and vibration modes, a Lock and Set level control, a night tracking light and waterproof construction. A mile sounds absurd until you have lost sight of a dog over a rise in a hayfield.
The one inch biothane strap is not optional here. Educator's own rule is to match strap width to the receiver rather than to the dog, and it lists the 1 inch strap for larger receivers and strong dogs where the extra width spreads load, in ten colors plus adjustable styles. The 3/4 inch strap that fits an ET-300 is the wrong part for this receiver, and a strap that is too narrow lets a heavy receiver rock.
The fifteen foot line is the same line we put in every e-collar kit, for the same reason. Educator calls it the unsung hero of recall training, says it gives the dog room to move while you keep a safety net, and states that the line comes off only once the response is reliable. On a big dog that line is also how you stay in the conversation when the dog decides the answer is no.
Beef heart is the payment. One ingredient, freeze-dried in small batches in Malvern, Pennsylvania, and it ships from us rather than from Educator. The texture is firm and snaps into small pieces, and it reads milder than liver, which matters if you are handing over forty rewards in a session rather than four. It comes in 1.5, 3 and 6 ounce bags. The whole range is on the freeze-dried dog treats page and grouped by use on the treats hub.
The holster is for people who work in fields rather than yards. Educator describes the range as duty grade carry, from leather through Kydex to a universal tactical mount, and points out that round transmitters in the ET and ME series take different holsters from the 900 series shape. Check which body you have before you pick.
Shipping is worth a line here, because this kit comes out of two buildings. E-Collar Technologies items are sold and shipped by E-Collar Technologies through Shopify Collective, not made or shipped by Sniff and Shift. The ET-800, the one inch strap, the long line and the holster all take that route. Beef heart is the exception and leaves our kitchen in Malvern under separate tracking, so you can start the fitting work before the treats turn up.
The part we left out on purpose
Contact points. Every large dog bundle we have seen online includes a set, and it is a coin toss unless somebody has looked at the dog. Educator states that the ET-800 ships with the 5/8 inch Standard Short point, and that on its own 302 breed coat chart, 163 breeds need something longer than what comes in the box. Look your breed up in the contact point finder, then order the length it gives you.
No GPS collar either. Tracking and training are different problems, and stacking a second unit onto a neck you are still fitting is a way to get neither right. If you want to see what else we carry for a dog this size, Explore filters the catalog by protein, life stage and format.
Working through the first month
Fit first, with the strap you ordered and nothing switched on. High on the neck, two fingers under the strap, points touching skin, and move the position every few hours. Big necks hide a badly seated receiver better than small ones, so check it more often than you think you need to.
Then find the level. A bigger unit does not mean a higher working number; you are looking for the same faint flicker of attention you would look for on a beagle, and most dogs sit near the bottom of the dial. Work on the line for two weeks before the transmitter does anything other than sit on your belt.
After that, add distance before you add distraction. A hundred yards in an empty field is an easier picture than thirty feet at a trailhead, and the line stays on through both.
What this replaces
A second collar bought after the first one disappointed. The usual sequence is a cheap unit, a period of inconsistency, and a jump to something stronger that does not fix the real problem. Buying the right receiver, the right strap width and the right point length once is cheaper than that sequence, and the line and the beef heart carry on being useful whatever you do next.
Questions
Is the ET-800 too strong for a seventy pound retriever?
Not if you use it the way Educator describes, which is a hundred low level steps with the working level set at the bottom of the range. Higher output means a wider dial, not a harder tap at the number you actually use.
Can I use my old 3/4 inch strap?
Educator sizes straps to the receiver, and the 1 inch width is the one it lists for larger receivers. Keep the old strap for a smaller unit rather than trying to make it work here.
Does the holster matter, or is a pocket fine?
A pocket is fine in a yard. In a field with a whistle and a line in your hands, the transmitter needs a fixed place or you will be patting yourself down at the wrong moment.
