This morning I've worked with both Tess and Rajah. I've started taking Tess in the car to different places and her focus and engagement was excellent this morning, ignoring other dogs, cyclists and runners. A couple of her actual movements/exercises aren't accurate enough (e.g. 'stand from sit') so I might need to go back to a garden session to refine these.
I'm learning more about Rajah and his feelings - I think he's quite a complex character. I took him to a recreation ground which was empty on arrival. On a trailing long-line I allowed him to sniff a limited area (about 20x20 yards) and after 5 minutes he oriented to me and was keen to 'work' (Rally exercises) and did so accurately. However when dogs appeared at a distance he stopped and stared at them. I just waited and when they had moved out of sight he again focused on me. Then someone with two dogs approached within a couple of yards and again Rajah froze and stared. The person was insistent that the dogs 'say hello' (despite me trying to explain that I was training and that he wasn't my own dog!) so in the end I released Rajah. He then had a sniff at the other dogs and looked much more relaxed, but didn't jump around or instigate play and when he glanced at me I said, 'Come' and moved away and he immediately fell into heel position.
I think he is showing what Denise Fenzi calls 'cautious curiosity', i.e. he is unsure about other dogs and can't focus on me because of this. Fenzi advises training at a distance from other dogs, but this is very hard to achieve in practice as I can't control other people's behaviour.
I'm wondering whether it would be better to take him to places where there are other dogs off-lead and simply not attempt to 'work' but just allow him to meet as many other dogs as he wants, but on the other hand he might find this overwhelming, and of course I'd need to make sure they were all happy encounters. Hmm perhaps not - I need to think about this some more.
