WAUDOG Smart ID is a free iPhone application developed by Collar LLC that focuses on pet identification and care. The app aims to help pet owners in ensuring the safety and well-being of their furry companions by providing a link between the pet's ID and profile within a global database of identified animals.

With WAUDOG Smart ID, users can store their pet's documents, track vaccination dates, schedule grooming sessions, and manage medication regimens through an intuitive calendar feature. The app offers a simple and quick registration process, allowing users to create separate profiles for themselves and each of their animals, with the flexibility to add details later on.
