Welcome!
Posting photos is pretty easy on the Dog Pictures page. Just click on "Upload" and follow the directions.
Serena (another member) and I are absolutely gaga for German Shepherds, especially GSDs that are working dogs, so we'd love to see your photos. And the Jacks are so full of life! I'll bet your Chihuahua has all sorts of fun playing with the Jack Russells. It must be a circus when they all get energetic.
What kind of things do your RCMP dogs do when they're working?
