I've helped take care of the family dogs since I was young. My father had hunting dogs when we lived in the country and those types were friendly but could be assertive. Feeding, watering and checking for ticks or small wounds was a daily routine in any weather. We had German Shepherds for security but they were also loyal and protective pets. I attended Vohne Liche Training Kennels in Indiana and became an Explosive Detection Dog Handler while working as a defense contractor in Iraq, and have the certificate. I currently don't have a dog since my yard is small and I know that a healthy dog needs daily exercise. I have taken care of my friends and neighbors' dogs and walked them daily, but I avoid taking them to city parks or dog parks. A few owners disobey the laws and allow their dogs to roam the park off leash and this almost always ends badly. Sooner or later there will be a fight when an off-leash dog decides to attack other dogs that are leashed. Not all dogs at doggy parks are well socialized, and there is no proof of any current vaccinations. Dogs are pack animals and some may try to assert their dominance by fighting or harassing other dogs, especially those that are well mannered and non aggressive.
