I'm at my wits end with our lovely boy. He's 3, he's always been a very nervous dog which makes him reactive to lots of things. With lots of training, behaviourists, patience he is much better. We're very careful about where we walk him, we know his body language, we know how to advocate for him on his walks and we keep him away from strangers in the home. It works well and we all love him. He's a small cocker spaniel.
Anyway, my dad is here doing some work on the house for us. Our boy is nervous of my dad, he loves him but is always timid and cautious around him. He was upstairs using a very loud sander (he hates motorbikes and my milk frother and my blender so I know it was the volume of it that he doesn't like). He escaped the kitchen, flew upstairs and went to attack the sander but caught my dad's hand instead. My dad's fine about it but I feel terrible, I feel like I've let him down.
How big of a deal is this? I have days where I despair of having to constantly manage him and this is one of them!
