Check your state law, county law and city law. Make sure your pets have their rabies shots. Identification tags, microchips and vaccination records are vital if your dog bites someone or gets lost. Check your city and county laws. Make sure your dog is spayed or neutered.
Most dog bites come from unneutered male dogs.
An unneutered male might break his leash to pursue a female in heat and run into the path of an oncoming car or fight with another dog. Know your dog. Know his personal language, like barks, growls and whimpers. Learn to read his tail, eyes, ears and body posture. Dog obedience class helps you understand your pet better.
