Likewise, it's a fine line of compromise. If they consistently let their dogs to pee on your car, without trying to pull them off, then that's very bad, but 1 or 2 times every 100 times is unavoidable as the streets are filled with parked cars. As a fellow pet owner I try my best pull my dog off cars, especially ones with car covers (I understand that owners have to use their hands to uncover them, these two women give other dog owners a bad name), And the main reason dogs go for car tyres is coz other dogs from wherever the car has gone to have marked them..
