Watch out for cuing/signalling for a negative response in your dog …
Try not to tighten and tense up your dogs lead when you spot another dog in the distance (this also applies to spotting other animals or people) and usually a road crossing is not needing when discovering them either ;-) These actions only perpetuate the signals to your dog, that yes indeed, there must be something off with that ‘creature’ if we are to ‘react’ this way.
Another, slightly different way to look at cuing is -
When you put your dog back on their lead after a recall, try if you can, to leave the lead long enough for slack. If you have the lead too short and tight each time after you get your dog back in, a negative association can form with coming back to you and being put on the lead - your dog has lost all that freedom, Selina McIntyre, Dog Behavioural Consultant & Dog Trainer, Dogs Best Friend.
