A dog training collar (also called an e-collar or remote training collar) lets you communicate with your dog at a distance using three signals: an audible beep, vibration, and adjustable static stimulation. Every INVIROX collar is designed by veterans who served alongside working K9 units, and built around one rule: start with sound and vibration first, and use the lowest effective level — never more.
Which INVIROX training collar is right for your dog?

|---|---|---|---|---|
| ULTRA K9 (flagship) | Reactive, stubborn or hard-to-train dogs; off-leash recall | 124 (beep 1–8, vibration 1–16, static 1–99) | Up to 1,100 yd | IP67 collar, IP65 remote |
| SPARK K9 | Long-fur and thick-coat breeds (bungee TPU strap keeps contact points seated) | 124 | 3,350 ft | IP67 collar |
| 2026 Edition | First-time e-collar owners; everyday obedience for dogs 8–110 lbs | 123 | 3,350 ft | IP67 collar |
| X2 System | Two-dog households — one remote controls both collars independently | 123 per dog | 3,350 ft | IP67 collar |
| ULTRA K9 X2 | Two powerful or high-drive dogs | 124 per dog | Up to 1,100 yd | IP67 collar, IP65 remote |
| ULTRA K9 Camo (Hunting Limited Edition) | Hunters and long-fur dogs 30–150 lbs — professional bungee strap + quick-snap nylon strap included | 124 | Up to 1,100 yd | IP67 collar, IP65 remote |

How to choose a dog training collar
Match the stimulation range to your dog, not the other way around. A collar with a wide, finely-graded level range (100+) lets you find the exact level your dog notices without overcorrecting — that is why all INVIROX collars use 123–124 levels instead of a handful of coarse steps. Sensitive dogs often respond to vibration alone; harder, high-drive dogs need headroom you will rarely use.
Coat matters as much as size. For double-coated or long-fur breeds (German Shepherds, Huskies, Golden Retrievers), choose longer contact points and a strap that keeps them seated — the SPARK K9's bungee strap exists for exactly this, and the ULTRA K9 Camo editions ship with the same professional bungee strap. For short coats, standard contact points are more comfortable.
Range is about your real training ground, not the spec sheet. Backyard and neighborhood-walk training rarely needs more than a few hundred feet; field recall, hiking and hunting justify the ULTRA K9's 1,100-yard range.
Training safely with an e-collar
An e-collar is a communication tool, not a punishment device. INVIROX collars include a security keypad lock to prevent accidental stimulation, and every kit ships with guidance on conditioning your dog to the collar first: pair the beep with a known command, escalate to vibration only if needed, and use static only at the lowest level your dog perceives. Sessions should stay short, the collar should be repositioned regularly, and puppies under 6 months should not wear a static collar. For step-by-step protocols, see our complete beginner's guide to safe e-collar training.
Frequently asked questions
Are dog training collars safe?
Used correctly, yes. Modern e-collars deliver adjustable stimulation starting at levels most humans can barely feel. Safety comes from the protocol: tone and vibration first, the lowest effective static level, short sessions, and correct fit. INVIROX collars add a keypad lock so a pocket press can never shock your dog by accident.
What is the difference between a shock collar and an e-collar?
They refer to the same category of device — "e-collar" and "remote training collar" are the modern terms, reflecting how current devices differ from older two-mode shock collars: today's collars lead with beep and vibration, and offer static stimulation in fine 1–99 increments rather than a single intensity.
Which INVIROX collar do professional handlers choose?
The ULTRA K9 is our flagship: 124 levels, night-light mode for low-light visibility, IP67 waterproofing and a 1,100-yard range. It is the model we recommend for reactive or hard-to-train dogs and for serious off-leash work.
Can I train two dogs with one remote?
Yes — the X2 System and ULTRA K9 X2 pair two collars to a single remote with independent level control per dog, so a correction for one dog never reaches the other.
What if it doesn't work for my dog?
Every INVIROX collar is covered by a 30-day return policy and a 1-year warranty, with 24/7 customer support.
