Amazon listing: Heaflex Dog Training Collar with Remote, 3300ft Remote Dog Shock Collar | IPX8 Waterproof Rechargeable E-Collar, 4 Training Modes (Night LED Light，Beep, Vibration, Shock) for Small Medium Large Dogs
The Heaflex Dog Training Collar is a remote e-collar system with a rechargeable receiver and handheld remote, and promo code 3TRXXNZB currently takes 24% off. If you have been comparing dog training price points before committing to a remote collar, the discount makes this one easier to fit into the budget.
It gives you four ways to get your dog's attention: a beep tone, vibration with 0 to 99 levels, a shock mode with its own 0 to 99 scale, and an LED light that makes your dog easier to spot after dark. The remote goes to sleep when idle to save battery, and it needs a wake-up press before any command button works, which cuts down on accidental presses in a pocket. Signal range is listed at up to 3300ft, and the receiver carries an IPX8 waterproof rating, while the remote itself is only splash-proof.
The adjustable strap runs from 8 to 26 inches and is listed for dogs from 15 to 100 lbs. To claim the deal, pick the 1-dog black version, drop it in your cart and enter the Heaflex Dog Training Collar coupon code 3TRXXNZB at checkout.

Who should buy it (and who should skip it)
This collar is aimed at owners working on recall or distance commands with dogs between 15 and 100 lbs, especially those who spend time at parks, lakes or open fields where range and water resistance matter. The LED mode adds value for evening walks. It is not the right pick if you prefer to avoid shock-based tools entirely, have a very small dog under 15 lbs, or need to train several dogs at once with this single-dog set.

Before you buy the Heaflex Dog Training Collar: quick tips
- Start with beep or the lowest vibration setting and step up gradually while watching how your dog responds.
- Keep the remote away from pools and heavy rain; only the collar receiver carries the IPX8 rating.
- Measure your dog's neck first and confirm it falls within the 8 to 26 inch strap range.
- Practice the two-step wake sequence on the remote at home before relying on it outdoors.

Heaflex Dog Training Collar coupon & promo code FAQ
What training modes does the Heaflex collar have?
There are four: a beep tone, vibration with 0 to 99 levels, a shock mode with 0 to 99 levels, and an LED light. The light is mainly for spotting your dog in the dark rather than for correction, so it doubles as a night-walk aid.
Is the Heaflex dog training collar waterproof?
The collar receiver is IPX8 rated, so it is built for swimming, rain and puddles. The handheld remote is a different story; it is only listed as splash-proof, so keep it dry and out of the water while your dog plays.
What size dogs does the Heaflex collar fit?
The strap adjusts from 8 to 26 inches and the listing names dogs from 15 to 100 lbs, covering many small, medium and large breeds. Measure your dog's neck before ordering, especially if your dog sits near either end of that weight range.
How do I use promo code 3TRXXNZB, and is there a coupon too?
Once the collar is in your cart, paste 3TRXXNZB into the gift card or promotion code field at checkout to take 24% off. The product page had no clip coupon when this deal was posted, so the code is the main way to save here.
Is 3TRXXNZB still working?
It was active when we last checked on Oct 23, 2026. Seller codes usually run 24–72 hours or until a set number of uses is gone, so apply it soon. Our team marks a code as ended as soon as members report it.
Is there a Heaflex Dog Training Collar coupon or discount code?
Yes – 3TRXXNZB is the current Amazon promo code (24% off). Amazon calls it a promotion code; it works the same way as a coupon or discount code at checkout.
Do I need Amazon Prime to use it?
No. Promo codes work for any Amazon account unless the promotion box on the product page says Prime-only.
Why didn't the code apply?
Usually a different size or color than the one the code covers, a one-per-account limit, or the code sold out. See all the fixes.
