Recently my Norwegian Elkhound 'Susi' overdosed on medication. Carprofen is toxic and can cause death, liver and kidney damage, as well as, ulcers if not treated immediately. Quick action in such a circumstance is vital in order to save your dogs life! Susi gave me motivation a year ago to invent a dog tag that weeks ago helped save his life! Now Susi has a permanent place on each and every tag!
