I have been walking my dogs; a Rescue Heinz 57, 2 Boxers, a Springer Spaniel and a Prince Charles everyday for 30 years. With my repeated discipline with my dogs during the walks, my dogs are both amiable and well behaved. The dogs do not bark, growl or even approach another dog passing by unless the the other owner ask if the dogs can meet. All my dogs have been in excellent shape. I am a marathon runner, therefore I walk the dogs (if given permission) at a fast pace. I do not wear head gear, or ear buds so that I can always hear and be cognizant of the needs and or issues that may occur when walking the dogs. Thank you for considering me!
