Yeah you are right...he does seem to get a little stressed/nervous at times. The annoying thing is I do constant training with him and he is perfect with all commands until he gets a scent or sees a deer (or a cat when he gets totally fixated!)...so I have been working on the watch me command more and more when out. Its very hard to get his attention when another dog is walking towards us, altho he will sit and stay....impossible to get his attention near where a cat is.
It is strange isnt it when they take a dislike to dogs for no reason....at agility on Fri he was impeccable....paid no attention to the other 2 entire dogs there, who he has previously had a fixation with, andwatched me whenever I asked him to, and funnily enough there was another dog there who we hadnt seen before (not entire) who seemed to not like Dylan initially! They were both on lead and I dont tend to let Dylan say hello to other dogs when he is on lead as he is best off lead....and the other one pulled towards him and growled! If only they could speak.....how easy would our job be then??!
