One thing that grinds my gears is loose dogs when I am walking Kaiser. The other day on the way to the dog park, a long haired dachshund came tearing across the front yard and attacked Kaiser.... He isn't used to aggressive dogs because he normally sees the dog park dogs. Well he proceeded to go after the dog. I pulled him back and the dachshund kept coming after him until the owner heard the noise and got her dog.... She then looked at me like Kaiser attacked her dog. That is the first time I have seen him be aggressive. But this happens more often then I thought it would. People need to keep a better eye on their dogs if they are off leash.
