To create a heart-shaped gradient design, first scissor a symmetrical heart into the coat, then apply OPAWZ Pet Hair Chalk in rainbow shades, blending from the bottom upward for a soft gradient effect.

How To Trim A Heart Shape On a Dog With Grooming Shears

Step 1: Prepare the Coat and Create the Base for a Heart Shape

Start with a clean, dry, well-prepared coat. 
Position a rectangular shape in the center of the dog's back. The design should sit along the body's center line and extend it evenly toward both sides.
Use a #5F blade to remove and shorten the surrounding coat, leaving the hair needed for the heart-shaped design.

     

Step 2: Find the Center Line

Locate the center line of the dog's back. This helps keep the heart symmetrical.
The heart design begins with a small V-shape in the center.
Create the V carefully and remove the excess hair inside the shape.
Keeping the center line accurate is important because it acts as the guide for both sides of the heart.

     

Step 3: Marking and Creating the Center V-shapes

Next, create a larger V-shape by working from the center outward toward the sides of the body. Repeat the same shape on the opposite side. At this stage, the basic outline of the heart should begin to appear.

Think of the design as being constructed from: Small V + Large V = Heart Shape

     

Step 4: Round and Refine the Heart with Grooming Shears

Once the basic heart shape is established, switch to dog grooming shears.
Use the center of the design as your reference point and work outward.
Connect the lines with smooth curves and remove any sharp corners.
Continue rounding the edges until the design looks soft, balanced, and symmetrical. The goal is to create a smooth, rounded heart with no harsh angles.

     

     

    

How to Create a Gradient Heart Design with OPAWZ Pet Hair Chalk

Once the heart shape is finished, it's time to add color.
Learn how to apply OPAWZ Pet Hair Chalk to create a smooth, eye-catching gradient heart design on your pet’s coat.

Step 1: Apply the Darker Color at the Bottom

Start with the darker colors along the lower section of the heart.
Apply the color gradually rather than trying to achieve full coverage in one application.
Using small amounts and multiple layers helps create a smoother and more controlled result.

     

Step 2: Layer the Pet Hair Colors Upward 

Continue applying the additional colors as you move upward through the design. 
In this tutorial, the dog chalk colors are layered to create a pastel gradient color effect. Allow each color to overlap slightly with the next color so the transitions do not appear harsh. 
For larger sections, use a larger brush to distribute the chalk more evenly.

     

Step 3: Blend the Transition Areas 

The key to a smooth gradient is blending the colors where they meet.
Instead of creating separate blocks of color, softly work the neighboring shades into each other.
For example: Dark color → blend into the next shade → continue upward
Apply additional color where needed to improve coverage and even out the gradient. The first application does not need to be perfect.
Build the color gradually and make adjustments as you go.

     

Step 4: Check the Final Shape and Color

Once the entire heart has been colored, step back and check the overall design.
Make any final scissoring or color adjustments needed before revealing the finished design.
The result is a colorful, heart-shaped creative grooming design with a soft pastel gradient.
