Which Dogtra E-Collar Fits Your Dog

For most owners it comes down to range and dog size. The 280X is the compact all-rounder, sized for dogs 10 lbs and up with a 1/2-mile range; the 1900X steps up to a 3/4-mile range and a tougher metal case for dogs 35 lbs and up; the ARC-X is the slimmest X-series receiver for smaller necks that still need range. If you are cross-shopping outside the brand, the Mini Educator ET-300 is the collar people compare Dogtra against most.

They are two different lines, not two sizes of the same collar. The 280X is the current X-series unit with 100 levels, a front-and-center main button and a 1000-lux LED light. The 280C is the Tom Davis edition with 127 levels, a customizable Boost button, a Safety Level Lock and a bungee collar. The full breakdown is on the 280C vs 280X page.

Owners who have used both report the 1900X as the stronger-output unit, while the 1900S is the older high-output design with 127 levels and a rheostat dial. The 1900X uses 100 levels with Tone, Vibration and a BOOST button in a metal case. The side-by-side is on the 1900S vs 1900X page.

Charge both the transmitter and the receiver fully until the LED turns green, then confirm they are paired before you blame the hardware. Most "not working" reports come down to a flat battery, a collar that is too loose for the contact points to touch skin, or the wrong dog selected on a two-dog remote. The step-by-step is on the how to use page and the button meanings are on the remote buttons page.

The parts owners reorder most are the collar strap, the charger, and the contact points. Straps are sized by width - most Dogtra receivers use a 3/4-inch strap - so a replacement has to match that width and your dog's neck size. The parts hub lists what fits which model, and the Handsfree Square is the add-on button that works across several X-series and Handsfree systems.

The current receivers carry an IPX9K rating, which is the top waterproof tier on the International Protection Marking scale - it means the unit has passed a close-range high-pressure spray test. In practice that covers rain, mud, splashing and submersion. The Handsfree Square add-on is the exception: it is not waterproof, which Dogtra states in its listing.

On most models, yes, by pairing an additional receiver to your existing remote rather than buying a whole second system. The 280X and 1900X both sell two-dog versions and standalone add-a-dog receivers, and the 280C 2.0 has a receiver-only option. Check that the add-on receiver matches your exact model line before ordering.

Dogtra does not list a standalone replacement remote on Amazon for its consumer e-collars - the transmitter is paired to its system. The realistic options are a warranty or paid repair through Dogtra directly, or replacing the system. The full situation, including what owners have done, is on the replacement remote page.
