Most owners see real change in the first 7 days. The 14-day plan moves in stages. Day 1 to 2 is conditioning and finding your dog’s working level. Day 3 to 7 is recall and the most important behaviors. Day 8 to 14 is locking it in around real distractions. Recall off-leash is usually solid by day 10.

Yes. The stim is current-limited in hardware so output cannot spike beyond safe levels even under fault conditions. The 124 levels mean you train at the lowest level your dog perceives, usually under 10, not at levels that cause discomfort. Following the 8-hour wear rule and rotating the collar position keeps the skin healthy long-term.

Dogs from 10 lbs to 150+ lbs. The strap adjusts from 9" to 27" neck circumference. Three prong lengths in the box cover everything from short coats to thick double-coats. For dogs under 10 lbs, call us first. We will recommend the right tool for your dog honestly.

Yes. The receiver is rated IP67 (fully submersible up to 1 meter for 30 minutes) and the remote is rated IP65 (rain-proof in any walking weather). Lake, pool, mud, snow, all fine.

The 124 levels are exactly for this. You start at the lowest perceptible level, and you almost never need to go past 5. The 14-day plan walks you through finding your dog’s working level on day 2. The level where your dog tilts his head and notices, not flinches.

You have 30 nights to use it on your dog. If your week does not change, send it back. We refund the full order, no restocking fee, no quiz. The risk sits with us.

Three things. Range: we hold 1,100 yards in real conditions, cheap collars drop at 250. Granularity: 124 levels vs. 10 means you find the right level instead of guessing. Plan: the box ships with a written 14-day protocol so you actually finish the training, not just buy hardware.

Yes. ULTRA K9 is built around an upgraded battery cell rated for 500+ charge cycles, a hardened stim circuit, and a TPU-reinforced strap. We back it with a 2-year warranty on the receiver and remote. If anything fails in that window, we ship a new unit. Not refurbished, not after a long investigation. New.

No. The stim circuit has a hardware current limiter that caps output at safe levels. The contact points are medical-grade stainless steel. Following the basics keeps the skin completely healthy: 8 hours max at a stretch, off at night, rotate the collar position every few hours, daily neck check.

Yes, with the long prongs (3/4") that ship in the box. For coats denser than 1 cm at the contact zone, trim a small strip on the contact points. It grows back fast and stays invisible. Thick-coat breeds typically work at a higher level than short-coat breeds. That is normal physiology, and the 124 levels are built to land exactly on your dog’s number.

The 124 levels are built for this. A Cane Corso might work at level 20, a Belgian Malinois at level 15, a Golden at level 5. All are normal. The 14-day plan finds your dog’s number on day 2. The key is a snug fit (one finger between collar and neck) so the prongs stay in contact when your dog moves, and starting at the right level instead of jumping past it.

Yes. The ULTRA K9 stim circuit is built around a hardened MOSFET and TVS protection that holds output stable over thousands of cycles. Every receiver is factory-tested at three points during production to verify stim strength before it ships. The 2-year warranty covers the receiver fully if output weakens.

Yes. The pairing holds through low battery, range edge, and power cycles. There is a hardware re-pair button directly on the receiver if you ever need to reset it. You should never lose the link mid-walk.

Yes. We fulfill from our own warehouse, so every unit is sealed, charged, paired, and tested before it leaves us. If anything looks off when you open the box, one photo to support and we ship a replacement same day.

Under 4 hours on weekdays, under 24 on weekends. Real humans, in English, Hebrew, or Spanish. WhatsApp, email, and the site chat all reach the same team. Setup, training, or warranty: same channel, same speed.

The silicone strap may have a faint factory smell on first opening, same as a new yoga mat or phone case. It airs out in 24 hours, or wipes off with a damp cloth and mild soap. Nothing transfers to your dog’s coat.

Yes, with the short prongs and a starting level of 1 to 4. The receiver is 65 grams. Light enough to sit comfortably on a 12 lb dog without unbalancing the collar. For dogs under 10 lbs, call us before you buy. We will tell you honestly whether this is the right tool or not.

The sensation at level 5 to 10, where 90% of training happens, is closer to a TENS muscle pulse than electricity. A brief twitch, half a second. We use the word “stim” because “shock” describes the wrong thing. Try it on your own forearm at level 7 with vibrate. That is what your dog feels almost every time.

The 14-day plan is built for first-time owners. Day 1 is just letting your dog wear the collar off. Day 2 finds the working level (head tilt, not flinch). Corrections do not enter the plan until day 5, after the foundation is built. Support replies in Hebrew or English within hours if you get stuck on any step.
