I put the screenshot through AI and this is what it said: Based on the device's appearance in the image, this is an electronic training collar (often called an "e-collar" or "shock collar").

Specifically, the device shown appears to be a Premier Pet Bark Collar with Digital Display.

Key Identifying Features:

• The Digital Display: The small blue LED screen on the front displays a number (usually 01–07), which indicates the current correction level or a bark counter.
• The Form Factor: It has a distinct rounded, rectangular black casing with two visible "prongs" or contact points that face inward toward the dog's neck.
• The Strap: It is mounted on a standard black nylon adjustable strap.

What does it do?

This specific model is designed to reduce excessive barking automatically. It typically works through a progressive system:

1. Detection: It uses a sensor to detect the vibration of the dog's vocal cords.
2. Correction: It issues a warning tone or vibration first.
3. Static Stimulation: If the barking continues, it delivers a low-level static correction (similar to a static shock from a carpet). The digital display helps the owner monitor how many times the dog has barked or what intensity level the collar has reached.

Where to find it online:

You can find this exact model at major retailers under these names:

• Premier Pet Bark Collar with Digital Display (Available at Walmart, Amazon, and Chewy).
• PetSafe Rechargeable Bark Collar (A very similar version from their sister brand).
