Michael Healy Labrador Retriever Door Knocker Michael Healy - Artistic Decorative Hardware All of Michael Healy's Dog Knockers are cast in solid bronze and handcrafted using the age-old art of foundry casting. During this process, molten bronze is heated to over 2200ºF and then carefully poured into a handmade sand mold. This mold is used only once, giving your Dog Knockers™ its individual character. Each Dog Knockers™ was treated with a dark patina, then hand polished and coated with a clear lacquer to protect its original finish. In order to confirm authenticity and quality craftsmanship, your Dog Knocker™ has been signed by artist Michael Healy. Michael has always enjoyed the company of dogs, especially Labrador Retrievers. Over the years, he has been the owner of several Black Labs. Pete, his first Lab, loved to long-distance swim with Michael along the Cape Cod shoreline. Pete was also an expert at fetching the newspaper, bringing it into the house each morning. Mandy was a trained hunting dog and accompanied Michael on many adventures. Alex, who currently lives with Michael, loves children and eating sticks. In honor of these great animals, Michael chose to make the Labrador Retriever his first Dog Knocker™. No matter which breed you love you're sure to find a Dog Knocker you will treasure.
