help My 1.5-year-old Border Collie suddenly became terrified of visitors and the doorbell after a stressful incident. How can I help him?
Hi everyone!
I have a 1.5-year-old male Border Collie who, until about a month ago, was always incredibly friendly and happy whenever someone came over. He never reacted negatively to the doorbell, people knocking, or visitors entering our apartment. In fact, he used to get really excited to greet anyone who came in.
However, over the past month, his behavior has changed quite dramatically.
Now, whenever someone rings the doorbell or comes into our apartment, he becomes extremely anxious and fearful. He starts barking, sometimes growling, and tries to hide from the person entering. This is completely unlike him, and I'm struggling to figure out how to help him feel safe again.
There are two things that happened around the time this behavior started, and I'm wondering whether either (or both) could have contributed.
1. His hormonal implant is wearing off.
About six months ago, we decided to try a temporary chemical castration implant rather than immediately opting for permanent neutering. We wanted to see how his behavior and personality would be affected before making a permanent decision.
The implant is now wearing off, and we've noticed physical signs that his testosterone levels are returning. I'm wondering whether these hormonal changes could be contributing to his increased anxiety or reactivity.
2. A very stressful incident happened at our front door.
Shortly before this behavior started, we had a really upsetting situation involving a family member we are no longer in contact with.
She showed up at our apartment completely unannounced, repeatedly and aggressively rang the doorbell, and forced her way inside despite being told to leave. The situation was extremely loud and confrontational, and our door/lock was actually damaged in the process.
My dog started barking intensely at her, which was understandable given the situation. Unfortunately, even though I explicitly told her not to approach him, she got right up in his face before I managed to move him into another room.
Once he was separated from the situation, he calmed down, but the whole experience was extremely stressful.
Since then, his reaction to the doorbell and visitors has completely changed.
I'm worried he may have developed a fear association with the doorbell and people entering our home. I also don't know whether the hormonal changes happening at the same time might be making things worse.
What I'm looking for advice on:
- How can I help him rebuild a positive association with the doorbell and visitors?
- Should I start by desensitizing him to the sound of the doorbell without anyone actually entering?
- How should I manage visitors in the meantime so that I don't accidentally reinforce his fear or push him too far?
- Has anyone experienced increased fearfulness or reactivity when a temporary hormonal implant was wearing off?
- Are there any specific training exercises or resources you'd recommend for this situation?
Unfortunately, I don't have access to a qualified behavior-focused trainer who can come to our home. There are puppy classes and general obedience trainers in my area, but not much support for this kind of issue.
I really want to handle this properly and avoid making things worse. I'm not expecting him to love every visitor again overnight, I just want him to feel safe and comfortable in his own home.
Any advice, similar experiences, or recommended resources would be greatly appreciated!
Thank you!
