It’s amazing how dogs pick things up.
I sometimes watch out the front window when I hear someone struggling to park - we have a lot round here and it’s not uncommon for them to bounce off your bumper (one guy did it to the van, luckily I saw and managed to stop him before he casually drove off. Cost him £350). Anyway, our dog clearly watched me and I think saw my stress level at that incident.
She learns the sounds of vehicles and gets it spot on - knows when the kids come home, knows granny’s Vauxhall, jumps up when I come back on the bike, and knows the sound a Mercedes sprinter so she can tell the shopping delivery guy how happy she is to see him as soon as he pulls into the road. She instantly learnt this guys engine note (and maybe driving style - high revs when parking) and now barks out the window whenever he’s trying to park near the van.
She watches it like a hawk if she hears anyone struggling to park, bless her.
