How to Use a Dogtra E-Collar

1. Charge both units. Charge the transmitter and receiver fully until the LED turns green. Do not skip this - a partial charge causes half the early problems.
2. Power on and pair. Turn both on and confirm the remote is controlling the receiver. On two-dog systems, check which dog the remote is set to.
3. Fit the collar. It should be snug enough that both contact points touch skin, high on the neck, with room for two fingers. A loose collar is the number-one cause of weak or missed corrections.
4. Find the working level. With the dog calm, start at the lowest level and step up until you see a small acknowledgement - an ear flick or a look. That is the baseline, not a training level.

Dogtra units give you graded stimulation (100 or 127 levels depending on the model), plus Tone, Vibration and, on many models, a BOOST button for an instant preset jump. The level numbers are not universal across models - a 30 on one collar is not a 30 on another - so re-find the working level any time you switch collars. What the individual buttons do is covered on the remote buttons page.

Before assuming the hardware failed, run this checklist: battery charged to green, collar snug with contact points on skin, correct dog selected on the remote, and contact points tightened. A surprising share of "no response" cases are a loose collar on a thick coat. If charging itself is the problem, see the charger and battery page. For a lost remote, see replacement remote.
