Universal size

The Petson no bark collar uses vibration to stop your dog from excessively barking all the time. 

There are two key points where the vibration is used, and this pulsing helps to distract your dog without causing pain or discomfort, allowing you to train them to stop barking unnecessarily.

It can even differentiate between your dog's bark and other loud noises to prevent false alarms. 

The anti-bark collar has 10 vibration signal combinations. When the dog barks, one of the two vibration points will vibrate. The duration of the vibration is random and interrupts your dog's barking. When used according to the instructions, the Vibration Control Collar will reduce annoying barking in most cases.

It also has a safety shut-off mode to stop constant vibrations in the case of dogs that just don't want to stop barking. It's set to shut-off for one minute if your dog barks 15 times or more within an 80 second period.

FEATURES:

• 10 different levels of vibration.
• It is suitable for use with any breed or size dog.
• A pain-free training method will help you get the results you want without hurting your pet.
• It can differentiate between your dog's bark and other noises.
• Adjustable strap can be fitted to your dog.

The durable unit is reasonably light at 260g which shouldn't bother medium to large dogs. It's also completely waterproof so you don't need to worry about rainy days.
