I have 2 dogs, a rescue springer mix and a bedlington. The problem is with the springer, who has now influenced the bedlington to behave the same way. It's being aggressive with people who are walking /running on their own without dogs-she's okay when there are dogs. She rushes up to them very fast and barks aggressively at them. This behaviour developed gradually, she used to ignore people as we walked by, with no interest in any interaction.
I manage this by putting her on the lead when ever I see anyone approaching, but would like to deal more effectively with this. She is good with recall except goes deaf when she's spotted someone (and I haven't seen them in time to put the lead on.)
How do I manage this? Keeping her on the lead all the time is a problem because she's such a high energy dog, and I would prefer not to always have to walk in remote areas where we won't bump into people.
