Spike reasonably calm in obedience

I took Spike to obedience last class, rather than taking the other two which is what I normally do. He had a few little grumbles at first, but after that I worked him through 4 15 minute classes off lead. OK he went up to the trainer a couple of times, but also worked very well. This was going past lots of dogs, most of whom looked at him. A couple barked during the classes, but he stayed focused. After the class I left him off lead and him milled and mixed with all the others really well. Great!
