I hate when people let their off leash dogs run up to my leashed dogs (we only walk in leash required areas). They always yell “they’re friendly” And I have to yell back “mine arent”. A suprising number of people still just mosey over slowly half-heartedly calling their dog while lm actively backing up and restraining my growling dog. One of my dogs is a rescue and she will fight anything if it charges her, a dog, a bike, a horse - she does not care.
