LUCKY DOG! is the true story of a friend's pet. It is shared to warn children that some dogs acting friendly may be dangerous. They should also know that most injured animals can be healed by veterinarians. Some vets help all sorts of animals--from dogs and cats to horses, cows, and pigs.Children should know collars, licenses, and shots are needed to keep their pet animals safe and to help them be found if they get lost. When a vet puts a chip with a phone number into a pet, it is not big like a potato chip but as tiny as a grain of rice. A radio scanner reads the information on it without hurting the animal.Lucky's story is also to encourage owners of potentially dangerous animals to have insurance to pay for medical aid for victims, if necessary.
