E-Collar BarkLess Pro BP-504 – Bark Collar for Medium & Large Dogs

E-Collar BarkLess Pro BP-504 – Medium & Large Dogs

Excessive barking is a real problem, and it's solved through communication and a methodical plan. The BarkLess Pro BP-504 by E-Collar Technologies is a professional bark collar with a smart mechanism: it identifies a genuine bark (not wind, not ambient noise, not vibration), starts at a low level and escalates gradually only if the barking continues, then resets to level 0 automatically after a pause. Built for medium and large dogs, 8–77 lbs.

How the BarkLess Pro works

The collar uses advanced bark-detection technology. It responds only to your own dog's bark and ignores outside sounds, begins with a gentle stimulation and increases only if barking persists. It cycles back to level 0 automatically after 30 seconds without a bark. 7 stimulation levels plus vibration and an audible tone-only mode.

Key advantages

• 7 stimulation levels + vibration + tone — starts low and escalates only when needed.
• Genuine bark detection — won't react to wind, ambient noise or vibration.
• Automatic reset — returns to 0 after 30 seconds without barking.
• Water resistant — IPX7 rated, works in the rain.
• Rechargeable battery — up to two weeks of battery life per charge.
• Lightweight (2.5 oz) — your dog barely notices it.
• Fits 8–77 lbs — a wide range of breeds.

Who it suits — and who it doesn't

Good fit: medium to large dogs (8–77 lbs) that bark excessively — at home, in the yard, or when their owners leave.

Less suitable: very small dogs (under 8 lbs), or dogs that bark only in one specific situation (for example, only when the doorbell rings) — in those cases working with a professional trainer is the better route.

FAQ

Does the collar hurt the dog?
No. The stimulation is designed not to injure or cause pain. It interrupts the barking humanely.

Does it work on long-haired dogs?
Yes, though with very dense coats we recommend considering longer contact points (25mm) so detection stays accurate.

How does it compare to the Dogtra YS300 / YS600?
The BarkLess Pro BP-504 is made by E-Collar Technologies and covers a wider weight range (8–77 lbs). The Dogtra YS300 suits small and medium dogs, and the Dogtra YS600 suits medium and large dogs.
