Why it matters

The ET-300 offers 100 stimulation levels plus tone and vibration so you can find the lowest level your dog notices. Both the miniature receiver and the floating remote are waterproof, and the kit includes two sets of contact points, a removal tool, dual charger, lanyard and clicker. It fits dogs over 15 lb with 10โ€“26 in necks.

Who it's for, and who should skip it

Good fit if

  • Low-level training
  • Water work
  • Trainer-guided use

Look elsewhere if

  • Dogs under the maker's minimum weight
  • Fearful or reactive dogs without a trainer
  • Owners wanting a quick fix for aggression

Pros and cons

Pros

  • 100 levels
  • Floating remote
  • Full kit

Cons

  • Price
  • Learning curve
  • 15 lb minimum

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.
