We sell quality dog products because we love dogs! The owners of Defending Champions are Australian Shepherd fans. Our hearts have been forever touched by our Thornapple Aussies. Each one we have had has its own unique story and has brought us much love and joy. We rejoice in our new puppies and are devastated when we lose one. Our sincere hope is that dog owners everywhere get as much love and joy from their dogs as we do. We encourage you to find something fun to do with your dog. Find fun dog activities here.
