Training Made Simple

All dogs are good,
but they are even better when trained.

Your dog wants to be good, they just don't always know how. Unwanted behaviors can be frustrating and even embarrassing. The best way to stop bad behaviors is to train your dog. You might say “easier said than done,” but OnGuard handheld dog trainer makes it easy.

It lets you give your dog instant feedback, right when the bad behavior occurs. This gives you control of the situation so you can train, treat and repeat your way to a better relationship with your four-legged friend.



OnGuard is great for training your dog any place, any time. It emits a high-pitched tone specifically targeted for a dog's hearing range. Most humans can't even hear it. Don't worry though – there's an indicator light that shows you its working. Use the ultrasonic function to deter your dog from unwanted behaviors like barking or jumping on the furniture.

Where to Use It

Bring it with you anywhere you take your dog. Toss it in your bag, backpack, purse or pocket. OnGuard dog trainer is always ready to help, at home or on the go.

How It Works

Every time your dog does something naughty – barking, jumping, leash pulling, etc. – simply point OnGuard at him and press the button. The ultrasonic tone will be irritating enough to distract him and stop his bad behavior, but without causing any harm. As soon as he stops the behavior, give lots of praise and treats!

Ultrasonic Sound

The star feature of the OnGuard allows you to simply point the device at your dog and push the button. He will hear a sound that you don't and he wont be fond of it. With time, your dog will learn that if he doesn't want to continue hearing this sound, he needs to be a good boy.

Safety Alarm

Ever been in a shady situation? With the OnGuard, next time you feel you are in danger you can simply press the panic button. A loud, pulsating alarm will sound and will not turn off until you tell it to.


The OnGuard's high-powered flashlight may just be the best you've ever owned. With 4,800 lux at 1 foot, this is one bright light. Use it while taking your dog out for his midnight potty break or simply use it for DIY projects around your home.

He is very friendly but loves to bark every time someone rings the doorbell, knocks on the front door, or passes by the front window. This video demonstrates how OnGuard can be used to help stop barking at the front door.

Ask a Question
  • What is ultrasonic sound?

    Ultrasonic sound is above the hearing range of humans, but is attention grabbing and irritating to dogs. This makes a safe and effective tool for dog training. It quickly takes your dog's focus off of barking and towards the high-pitched sound.

  • Can I use this to train my puppy?

    Due to the powerful nature of this product, we do not recommend it for use on puppies under 1 year of age as they are still developing their hearing.

  • What's the blue light on top for?

    The blue LED light on top of the unit indicates the ultrasonic button has been pressed and ultrasonic sound is being emitted.

  • What is the range?

    The ultrasonic frequencies can be heard by dogs up to 50 feet away.

  • Will OnGuard work on dogs in other rooms or on the other side of a fence?

    Ultrasonic sound cannot travel through solid objects like walls or solid fences. Make sure OnGuard is in clear line of sight of the dog you wish to train or deter.

  • Will this hurt the dog?

    No. Although the ultrasonic sound emitted by OnGuard is a great tool for training, it is physically harmless to dogs.
