I’ve owned dogs for many years and thought I had it figured out—food, vet appointments, training, dog toys all over the place—but I had never thought about the color of a dog’s collar. A dog’s collar cannot be overlooked as mere embellishment; it can be considered a sort of communication. It was surprising to realize that a whole expression of unspoken language existed that so frequently goes unnoticed.

What I remembered most out of all the colors was red. Red collars. Red bandanas. I kept seeing references to them and thought to myself, “What’s the big deal, it’s just a color?” Except, nope. It is not just fashion. Red is basically a massive “give me space” sign for dogs.

The Significance of a Red Collar

Here is what I learned: when you see a dog with a red collar or sometimes a red bandana on, it is not just because the owner thought it looked bold or festive. That red is a signal. The signal means that dog might not want you running up with your hand out or letting your child run over squealing, “puppy!” There is a kind of shorthand in the dog world. A red collar signifies you should proceed with caution. So does that mean every single red-collared dog is aggressive and waiting to snap? Not at all. There are many layers of truth here. Dogs, like us, have moods and their own comfort zones. Maybe that dog is perfectly mellow at home but overwhelmed by a stranger in a park. Maybe the dog has had a rough ride and is still sorting out how it wants to feel safe. The red collar is their owner’s way of saying, “Hey, my dog has boundaries. Please respect them.”

The Most Important Thing to Remember

The next time you see a dog with a red collar or bandana, you don’t need to panic or assume the dog is dangerous.

Just pause.

Give the dog room, keep your children and pets close, and avoid reaching out without permission. The red accessory may be the owner’s way of communicating a boundary that the dog cannot explain for itself.
