Shelley Brooksville, FL 4/25/2011 6:52:09 PM Bruce, First, it is not fair to target Pit Bulls, any dog that is constantly chained, tethered, or always restrained and just left to it's own devices, will make an effort to get free. if the owner who does not have a fenced yard (like me) tethers their dog for a few minutes so they can go potty, then that is ok ( just my opinion). I do put my dog on a tether for no longer than 15 minutes and I am always right on my screen porch watching him. I agree that leaving a dog tethered for any length of time is unreasonable and creates problems. Owners of all breeds need to be responsible and make sure their dogs are well socialized to other animals and humans. i don't think it is breed specific. i work with the Humane Society and have met dogs that are more aggressive than own pits, it is socialization that is a key component.
