Early Black Friday Sale
Calm Your Dog Without Raising Your Voice
When your dog barks at strangers, pulls toward distractions, or ignores your commands on walks, you need a tool that redirects attention instantly. This handheld ultrasonic training device emits a high-frequency tone—audible to dogs but silent to humans—that interrupts unwanted behavior the moment you press the button. Three adjustable training modes let you match the correction level to your dog's temperament and the situation at hand. The rechargeable design means you're always ready, and the compact ABS body fits easily in your pocket or bag. You train with calm consistency, building trust instead of tension, and your dog learns boundaries without fear or pain.

Why You Need This
- Instant Attention Redirect: The ultrasonic pulse stops barking, jumping, or chasing the second you press the button—no yelling required.
- Three Training Modes: Adjust intensity based on your dog's sensitivity and the behavior you're correcting, so every session is effective.
- Rechargeable & Portable: USB charging keeps the device ready for daily walks, and the lightweight build slips into any pocket.
- Gentle, Pain-Free Correction: High-frequency sound interrupts behavior without causing discomfort, so you reinforce commands with confidence.
- Works Across Situations: Use it for barking indoors, reactivity on leash, or unwanted jumping—one tool for every training challenge.
- Builds Consistency: Pair the ultrasonic signal with a verbal cue, and your dog learns faster through predictable, humane correction.

What Our Customers Say
Discover what makes THOMLER special.
Pocket-sized and rechargeable—exactly what I needed for morning walks around the neighborhood.
Finally something that stops the jumping without me having to raise my voice constantly.
I've been using this for about three weeks now, and my lab's reactivity toward other dogs has genuinely improved. The consistency of the tone paired with treats has clicked something in her head.
The build quality feels solid, and I appreciate that it's truly silent to my ears. My neighbors no longer have to hear correction attempts echoing through the yard during training sessions.
Took a minute to figure out which mode matched my dog's temperament, but once I dialed it in, the unwanted barking during doorbell time dropped off noticeably within the first week of regular use.
