‘Tie a yellow ribbon round the old oak tree’ – do you remember that song? It was a song by Dawn that featured Tony Orlando. The person in the song had been sent to prison and was finally coming home. The yellow ribbon meant that he was welcome to come back home.
But, if you see a dog with a yellow ribbon, vest, bandanna, or scarf it has a completely different meaning.
The owners of the dog put the yellow item on the dog as a warning. Just like a yellow flashing light means caution – so does some yellow on a dog.
