BullyBillows TRI-Harness® – Anti-Pull Y-Shaped Dog Harness

The BullyBillows TRI-Harness® is designed to provide a secure, comfortable and non-restrictive walking experience for dogs of all sizes. Combining the former Mini and Standard versions into one complete range, it offers the same ergonomic design from XXS through to D, making it easier to find the right fit for puppies, small breeds, large dogs and strong pullers.

Built around a Y-shaped frame, the TRI-Harness® is designed to support natural shoulder movement while reducing pressure around the neck and throat. Soft neoprene lining helps improve comfort, while three attachment points give owners flexible control for everyday walking, training and management.

Three Lead Attachment Points

The TRI-Harness® features three strategically positioned attachment points, giving you multiple options depending on your dog’s needs.

The front D-ring can provide additional steering and anti-pull assistance, while the other attachment points allow you to adapt the harness for everyday walking, training or increased control.

Non-Restrictive Y-Shaped Design

The ergonomic Y-frame construction is designed to sit around the shoulders without unnecessarily restricting movement.

This helps dogs move more naturally, making the harness suitable for everything from short neighbourhood walks to longer outings.

Soft Neoprene Lining

A soft neoprene lining helps cushion the harness against the body and reduce rubbing against the coat and skin.

This added comfort makes the TRI-Harness® a practical choice for regular wear, puppies, sensitive dogs and longer walks.

Size-Specific Webbing

The harness uses different webbing widths depending on the dog’s size:

• XXS / MINI A and XS / MINI B: 2.5cm webbing
• A, B, C and D: 4cm webbing

This allows the smaller sizes to remain lightweight while providing increased strength and surface area for medium and larger dogs.

Secure Buckle System

High-strength buckles make the harness easy to put on and remove while helping maintain a secure fit during walks.
