Thanks a lot for your kind and helpful comments guys! The bit about the tail is very interesting, and mostly it is in the 'friendly' position. We talked to our trainer and she's going to come and do some clicker training and get us fixed up with a watch me command, so spot on advice! Today we went to the local dog park and our lad ran free with some other doggies. He was a little reserved and stay on the fringes initially, but he started to enjoy himself and at one stage he was tearing around in circles with the other doggies lagging behind him
It was so much fun and we really enjoyed it. Today we met another rescue doggie on the street and Scruffy had a little bark, but they ended up sniffing each other calmly and tails were wagged, so another nice positive experience. Phew!
