We have two sizeable dogs....a Swissy mix at 101 lbs and a Boxer at 85 lbs. When they are in the yard (Invisible Fence) they are free to roam. Any other time they are on a 5 ft. leash. When I ride I carry pepper spray and occasionally have a .32 Keltec in my seat bag. I know this sounds paranoid but if you knew me you'd know I am not. Having been an Investigator for the State of CT I have encountered my share of aberrant behavior. Life is beautiful until it's not as mentioned previously. I don't intend to pay the price for someone else's bad judgement or intentions.
