6 Significant Dog Collar Colors and Meanings Capuski - Getty Images

When it came time to order a new leash for our miniature schnauzer Aldo, we chose one that matched his collar – a nice, bright yellow with reflective stitching that accentuates the design. It was only after we started walking him and people were asking me if it was ok to pet him based on the color of his collar that I realized a dog's collar color had meaning.

About 25 years ago, a dog trainer in Australia introduced a yellow ribbon movement that grew into the Yellow Dog Project, wherein yellow ribbons and bandanas are used to convey a dog’s level of comfort with being approached by people and dogs, and that they need more space.

The idea is evolving into a color coding system that’s being implemented around the U.S. Some animal rescue organizations have adopted the system, incorporating color coding into their work with dogs up for adoption. The Continental Kennel Club is fully onboard, and has identified the main colors that may be displayed through collars or leashes and what they convey when it comes to dogs: red, orange, yellow, green, blue, white and purple.

Read on to gain a better understanding of dog collar colors and meanings. Keep in mind, though, you will always want to check in with a dog’s person before approaching to say hello.


Red

Just like road signs, a red dog collar means stop. Red doesn’t necessarily mean that a dog is aggressive, but she may not be keen on meeting new people or dogs out on a walk.

Green

Green means “go” when it comes to dog collars, conveying that the pup is friendly. When we adopted our girl, Scout, we happened to choose green for her collar and leash. It turned out to be the perfect fit – she loved every person (and most dogs) she met.

Yellow

There are two meanings when it comes to yellow collars: the dog may need some space to warm up to people or other dogs, or he may be up for adoption.

White

If you come across a dog wearing a white collar, it may indicate that she’s deaf and/or blind. That’s not to say that she’s not friendly, but may be frightened if approached unexpectedly.

Orange

An orange collar indicates that a dog isn’t keen on interacting with other dogs, though he may be ok with meeting new people.

Purple

A big fan or the Cheerios that are doled out during our morning walks with neighborhood friends, our Aldo would be horrified to wear a purple collar, an indication that he should not be fed.
