Osteosarcoma accounts for 80-85% of all canine skeletal tumors, and large breed dogs such as Greyhounds, Great Danes, Labradors and Rottweilers are 150 times more likely to develop this cancer. The wonderful folks at 2 Hounds Designs have a special new line of collars available, in an effort to raise awareness of (and funds for the fight against) Canine Bone Cancer. 
The words, Hope, Love and Believe are imprinted on the ribbon, mingled with the playful silhouette of a Greyhound (art by Xan Blackburn). The ribbon is layered against any one of several color options, and can be made in Buckle, Tag and, of course, Martingale Collar styles. Several sizes and widths are available, and you can also add a leash to coordinate. The leash is lined with velvet ribbon, so you'll have that extra soft handle for your walks.
Beautiful headbands and key fobs are also available, making the perfect gift for the Greyhound lover in your life.
