It is possible to use vinegar to prevent dogs from peeing, but vinegar only removes the smell and cannot truly control dogs from peeing. Moreover, the smell of vinegar is not good, so spray it too much in the house. The smell will be very strong, so it is recommended that the dog still needs to be trained. There are generally two methods to prevent dogs from urinating randomly. One is to walk the dog on time every day, and the other is to train the dog to urinate at a fixed point.
