Consider yourself lucky that Diesel is just trying to scare balloons away......I have a Lab/Dal mix who has decided that the existence of skunks is meant as a personal insult to her.......most dogs learn better than to mess with skunks after one spray, Lady has decided that all skunks must die.........they spray her, and she just goes after them harder. One time she had one cornered under my truck.... (that was a fun trip to the car wash......)
