Stop walking your reactive dog.
A ridiculous statement, right?
Maybe not…
Sensitisation is when repeated exposure to a stimulus leads to an increased response over time.
For example - your dog reacts to another dog on a walk, You carry on walking as normal, perhaps hoping they’ll get used to it or grow out of it. But over time, your dog may become more reactive…
reacting sooner & more intensely, pulling harder, scanning their surroundings & becoming increasingly hypervigilant.
Repeatedly facing something they find threatening or overwhelming, without enough chance to recover, can keep a dog’s nervous system on high alert. They may then become more watchful & quicker to respond, with less distance or change needed to trigger a reaction.
There’s also the added risk of generalisation.
- A dog that was once reactive to small dogs may begin reacting to all dogs, then to the area where they first encountered one & eventually to other places too.
These patterns can be difficult to overcome & if the problem continues, it may gradually get worse.
If you need help or guidance, look for a qualified behaviourist with experience in behaviour modification for help.
