Ive been using TT with my 4yo GSD Lexie. Shed competed in Working Trials for 3 months when she was given homeopathic pulsatilla by our vet to increase the time between her seasons. An unexpected side-effect was that she lost her sense of smell & tracking was impossible. I continued entering her for competitions until I realised. She was puzzled and unhappy not to be able to do as I asked her. When her sense of smell returned I restarted her from scratch & she enjoyed it again - except at competitions. I used TT to calm her & give her good thoughts about tracking- its restored her confidence & shes now competing happily. Its also great for calming dogs before a downstay. Thanks James
