Answer to:
Why do dogs pee on fire hydrants? As we all know, dogs urinate to "say Hi". Sort of like leaving a comment on myspace... In todays society it may be the only social interaction they have with other dogs. The reason dogs urinate on fire hydrants is this: They want to leave their urine on the HIGHEST point possible. The higher the urine, the bigger the dog... Obviously a great dane is going to be able to urinate...
