HOW THE HOLIDAY CAME TO BE

Sarah Jones, founder of My Anxious Dog in the United Kingdom, created Dogs in Yellow Day in 2022 after her Cocker Spaniel Bella was attacked as a puppy and developed a lasting fear of other dogs. Jones designed yellow products to signal that a dog needs space and launched March 20 as the annual awareness day.

INTRO

Introduction

PHOTO

When Sarah Jones's Cocker Spaniel Bella began lunging and growling at approaching dogs after a puppy attack, strangers on the pavement responded with eye rolls and tutting, not sympathy. Dogs in Yellow Day grew out of that frustration: a yellow harness, lead, or bandana that tells the world "this dog needs space" before a single bark is exchanged.

The color yellow was not chosen arbitrarily. It draws on a decade-old international convention, rooted in Sweden and adopted across dozens of countries, that treats yellow as the canine equivalent of a traffic caution signal. The system works because yellow is one of the most visible colors at distance, giving approaching walkers time to redirect before a reactive dog is triggered.

ORIGINS

Dogs in Yellow Day history

INTRODUCTION

The idea that certain dogs need visible signals to warn others predates any single holiday. Dog trainer Terry Ryan is credited with introducing yellow ribbons and bandanas in her training classes as a way for handlers to flag dogs that should not be approached. Australian dog trainer Pat Robards brought the concept to dog clubs in Australia in the early 2000s.

The first organized program came from Sweden. In 2012, Eva Oliversson launched International Gulahund Yellowdog, a trademark-backed initiative that designated yellow as the universal color for dogs requiring extra space. The concept spread quickly: by 2013, Canadian dog trainer Tara Palardy had started The Yellow Dog Project, which gained significant online traction and helped establish yellow as a recognizable signal across North America.

CHAPTER 01

Why Yellow Works

Yellow was not picked at random. In traffic systems, signage, and hazard labeling, yellow universally signals "proceed with caution," a meaning that transfers naturally to a leash or harness. The color carries no implication of aggression; it simply communicates that the dog may be fearful, in training, recovering from surgery, or otherwise unable to handle uninvited interaction.

CHAPTER 02

Bella's Story and the Birth of the Day

Sarah Jones experienced the problem firsthand when her Cocker Spaniel, Bella, was attacked by another dog as a puppy. The attack left Bella reactive and fearful, causing her to growl or lunge when unfamiliar dogs came too close. Passers-by assumed Bella was aggressive, responding with disapproval rather than understanding.

Jones began designing yellow harnesses, leads, and collars printed with messages like "Keep Dogs Away" through her brand, My Anxious Dog. The products gave owners a clear, non-verbal way to communicate their dog's needs during walks.

CHAPTER 03

From Products to an Awareness Day

In 2022, Jones formalized the movement by establishing Dogs in Yellow Day on March 20, encouraging what she calls the "Yellow Army" to share photos, distribute awareness materials to veterinary clinics and pet shops, and educate their communities about what yellow gear means. The observance has since expanded to include organized events, including a 2024 awareness walk at Cliveden House in partnership with the National Trust.

Yellow Dog Project reaches Canada

Canadian dog trainer Tara Palardy launched The Yellow Dog Project, inspired by the Swedish initiative, and attracted over 12,000 participants through social media.

Finnish study quantifies dog anxiety

A peer-reviewed study in Scientific Reports analyzed nearly 6,000 dogs and found that 72.5% exhibited at least one anxiety-related behavior.

Dogs in Yellow Day established

Sarah Jones launched Dogs in Yellow Day on March 20 through her My Anxious Dog brand in the United Kingdom, creating a dedicated annual awareness day for reactive and anxious dogs.

Guide Dogs UK anxiety survey released

A Guide Dogs UK study found that 74% of UK dogs, roughly 8.8 million animals, displayed signs of anxiety or depression.

Third annual observance grows globally

The 2024 Dogs in Yellow Day included an organized awareness walk at Cliveden House with the National Trust, expanding the observance beyond social media.

GET INVOLVED

How to Celebrate Dogs in Yellow Day

Outfit your dog in yellow gear

If your dog needs space, equip them with a yellow harness, lead, or bandana that communicates their needs before anyone gets close. My Anxious Dog sells purpose-built yellow products with printed messages like 'Keep Dogs Away' and 'Anxious.'

DISTRIBUTE

Distribute awareness materials to your vet

Order or download the #DogsInYellow awareness pack, which includes posters and stickers, and ask your local veterinary clinic or pet shop to display them. Waiting rooms are one of the most effective places to reach owners who may not yet recognize what yellow gear signals.

LEARN

Learn to read canine stress signals

Study the ladder of aggression, a visual guide showing the escalating body language dogs display before they snap. The Blue Cross publishes a free guide to canine body language that covers lip licking, whale eye, and other early warning signs.

Share your dog's story on social media

Post a photo of your dog in their yellow gear on March 20 using the hashtag #DogsInYellow. The campaign's strength comes from volume: the more owners who post, the more non-owners encounter the yellow-gear concept in their feeds.

RESEARCH

Research force-free training methods

Reactive dogs respond best to training approaches that build confidence rather than suppress behavior. The American Veterinary Society of Animal Behavior publishes position statements supporting reward-based training, which outlines the evidence against punishment-based techniques for fearful dogs.

WHY THIS DAY MATTERS

Why Dogs in Yellow Day is Important

A visual system reduces preventable incidents

Yellow gear functions as a standardized, distance-readable signal that allows approaching walkers to give space before a reactive dog is triggered. This simple visual cue can prevent the kind of uninvited approaches that undermine ongoing training and rehabilitation for fearful dogs.

Most dogs carry hidden anxiety

A 2020 Finnish study of nearly 6,000 dogs found that 72.5% exhibited at least one anxiety-related behavior, with noise sensitivity affecting 32% and general fearfulness affecting 29%. A separate 2022 Guide Dogs UK study estimated that 8.8 million dogs in the United Kingdom, roughly 74% of the canine population, showed signs of anxiety or depression.

Post-lockdown puppy boom strained socialization

Half of UK veterinarians reported a rise in client concerns about dog aggression following the pandemic-era puppy boom, with 87% of the aggressive dogs being under three years old. Restricted socialization windows during lockdowns left many young dogs without the early exposure needed to develop confident, non-reactive behavior.
