The mark is comprised of a three dimensional object, namely a pet chew resembling a toothbrush with a bone knuckle shape at the opposite end of the brush shape, and the word "NYLABONE" on one side of the object and the word "NYLABONE" beneath the image of a stylized image of a dog's head on the other side.
The shading in the mark is not the feature of the mark but is intended to depict the three-dimension of the mark.
