It is blue

no they don't

The word "blue bark" is an old Navy term, from the days of the Ships-of-the-line. War ships could be identified by a gold line the adorned the trim of the ship. When the captain of the ship, or another shipmate, died while in battle (and eventually just at sea), the gold line was painted blue to allow other ships and those waiting at the dock time to render honors. The term "blue bark" comes from this tradition of painting the bark blue and is at least as old as the USS Constitution.

Hi i have a blue heeler who is 4 years old. She is a great loyal and smart dog and only barks when somebody comes to the house. she is great protection. Blue heelers generally do not bark often as they are smart dogs and will listen when told something. That's why they are used on farms lots. The only reason my blue heeler while continously bark is if se no's if something i wrong.

There are two ways to get the blue bone, to find it on a walk, or have someone to give it to you through bark mode
