OnGuard Training Tips: Barking At The Front Door
Our customers' favorite use for OnGuard is to deter barking at the front door. Here we will share our training tips to solve this common behavioral issue.
You’re familiar with the scene… Someone knocks at the door or rings the bell and your dog goes berserk. Frustrated you speed to the door, rehearsing your apology for the whomever is on the other side.
As soon as your dog starts barking, calmly stand up and walk to the door. Never yell at your dog for barking, it will increase his energy level and make the problem worse.
Step in front of the dog, positioning your body between him and the door.
Point OnGuard at the dog then press and hold the Ultrasonic button.
Take a step towards the dog, essentially using your body to push him back from the door.
For extra stubborn dogs you can activate the strobe light feature in addition to the ultrasonic sound.
Once the dog has backed away from the door, let go of the sound & light buttons. Allow him to calm down for a moment and then open the door.
Remember to reinforce your dog’s good behavior, as soon as they do what you want. Give him a small treat / verbal praise / pet them to let them know you’re happy with their good behavior. Keep your OnGuard close by so that when training opportunities come, you’ll be ready.
You can modify these steps as needed to work for your training situation. Train, Treat & Repeat!
Results are not immediate. Training steps should be repeated as often as necessary to teach your dog when his behavior is not acceptable — but also that he will be praised for his good behavior.

Frequently Asked Questions
What is ultrasonic sound?
Ultrasonic sound frequencies are above the hearing range of humans. Although this noise is inaudible to most humans, dogs hear it loud and clear. This high-pitched noise is alarming and unpleasant to dogs being targeted, but completely safe and humane.
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.
Can I use this to train my puppy?
Due to the powerful nature of this product, it is not recommended for use on puppies under 6 months old as they are still developing their hearing.
What’s the blue light on top for?
