Your dog is too small You will have to try it on. Perfect fit - congrats!

To ensure effective training and dog's safety, you must properly fit the collar on your dog. The collar must fit snugly to allow “contact points” to have a direct contact with the skin. Position the receiver unit high up on your dog's neck just below the ears.

You should be able to fit two fingers between the collar strap and your dog's skin. Too tight poses the risk of skin irritation and discomfort. Too loose and the contact points will not be able to administer the stimulation reliably and can cause skin irritation due to chafing. Cover the contact points with conductive rubber caps to reduce the risk of skin irritation or injury.

CAUTION: E-collars are not designed to be worn constantly. We recommend using the e-collar only under adult supervision and for no longer than 4 hours per day. NEVER attach a leash to an e-collar. Use a separate regular collar if there is a need for a leash.

Yes, you can cut the collar strap to the desired length.
Your pup should be old enough to understand basic commands. So, your dog should be at least 5-6 months old.
No, this can result in pulling the contact points to tightly against your dog's neck causing the injury. Use a separate collar when needed.
Longer contact points are required for dogs with long thick hair, so they could easily reach dog's skin. Sometimes it is necessary to slightly trim your dog's hair around the neck. However, it should not be shaved completely to avoid skin irritation or injury.
Training sessions should be kept short and positive around 10-15 minutes.
No, you can charge it separately.
We do not recommend to use the collar on aggressive dogs.

Product Features

No, the rechargeable battery is built-in and it cannot be replaced. It's designed to last for a few years similar to smartphones batteries.
It depends on the model. You can find the exact distance in the product description. Please note that advertised range is applicable to the ideal laboratory conditions. The range may vary depending on the terrain, buildings, trees and electromagnetic interference from other devices.
The collar enters into the sleep mode after 1 minute with no motion (when your dog sleeps for example). As your dog moves or shakes, the movement sensor will automatically activate the collar. This technology saves battery life and allows collar to work longer without charging. There is also a power button that allows you to turn the collar completely off.
It depends on the intensity of training sessions and may vary from one day to one week.
The Receiver Collar is fully waterproof. Nevertheless, we do not advise it for long swimming sessions. It’s fine if your dog jumps into water and comes out. Heavy rain is also not a problem. The Remote Transmitter is not waterproof (excluding models P620 and P620B which are fully waterproof).

Pet care

The max amount of time you can deliver the vibration or static shock to your dog continuously is 10 seconds. After 10 seconds the remote transmitter will time out. The vibration or shock button must be released and pressed again.
It is highly recommended to limit the continuous shock delivery to no more than 3 seconds (the smaller the dog the shorter it should be).
Stop using the product immediately for at least 48 hours. If the condition persists beyond 48 hours please consult your vet.
The collar is not design to be worn continuously. We recommend the collar to be worn only during training sessions or other outdoor activities. Avoid leaving collar on dogs for more than 4 hours per day.
