DoggieDiggz's pet ID tags are made from local exotic wood in San Diego. Laser engraved with our designs, and personalized for your pet. Our tags are unique in the way that they are lightweight, non-toxic, and eco-friendly alternative to metal tags. Our tags are engraved on 3 different woods: Avocado, Sugargum Eucalyptus, and Black Acacia. We suggest different woods for different dogs because of their durability. The Sugargum Eucalyptus is a great wood for very active dogs that hike or visit the beach often. Avocado is a great one for smaller pups, or the classic "couch potato". Black Acacia is a very dark hardwood stands out great on light fur and is also good for active dogs. Price for our tags are $20 including a design and pet information on the back.
