Dogtra ARC-X: 3/4 Mile, Boost, XPP Vibration, Up to 3 Dogs

Why it matters

The ARC-X has a slim 2.75 oz receiver and 3/4-mile range. A Boost function and a safety level lock help keep stimulation consistent, and XPP vibration and an audible tone offer non-static cues. It expands to three dogs and Dogtra states IPX9K. It fits dogs 15 lb and up.

Limitations to weigh

Static stimulation is an aversive. Many vets and welfare groups advise reward-based training first and a qualified trainer before using any e-collar; start at the lowest level that gets a response and never use it in anger.
Check fit daily, move the receiver every few hours and limit wear time (makers commonly say no more than 8 to 12 hours a day) to avoid pressure sores.
Range figures are the maker's open-ground numbers; trees, hills and buildings cut real range.
