UNLOCK: push the clasp lock away from the opposite side.

5.5 Check the Final Fit

Place the collar on your dog.

Adjust the Spray Angle

Collar Science adjusts to your dog’s unique face shape, from pug to beagle and beyond. The right spray angle ensures the most effective training.

⚠️ ALWAYS adjust the spray angle while the collar is powered OFF.

The correct position is for the spray to go directly in front of your dog’s nose.

The spray should not go under the chin or too far out in front of the face.

To adjust, twist the tank handles until the spray unit is aimed in the correct position.

This may take a few tries to get the angle just right for your dog.

Correct angle = most effective spray + best results.

Adjust the Spray Volume

Our Bark Collar has 3 spray levels: Low, Medium, and High, designed to match your dog’s unique sensitivity.

Each collar starts on the Medium setting. 

Start at this setting to see how your dog responds.  

If your dog needs strong reinforcement switch to High 

If your dog is very sensitive switch to Low

💡 Training Tip: Many dogs learn quickly with consistent use. Once your dog understands the correction, a lower spray setting often works just as well saving spray while keeping training effective.

How the Bark Collar works

Our collar is designed to train appropriate barking by allowing one bark before delivering a correction. The spray correction is automatically triggered by your dog’s bark.

First bark: Tone warning (the collar will beep but wont spray)

2nd Bark: Spray Correction 

After 2 minutes of quiet, the collar resets and will allow another warning bark
Title

Smart, Automatic Bark Correction

The collar uses smart detection technology to identify your dog's unique bark using both sound and motion. This helps prevent false correction from other dogs or background noise.

Title

When to Refill

You can monitor your spray level by looking at the clear tank on the side of the collar.

When the tank is low, remove the collar from your dog 

Refill using CollarScience spray refill cans only
