For people who want their dogs to be off leash, there are a variety of dog parks. Most parks have rules, but be careful. Even if it's an area where your unleashed dog is allowed, remember that you are putting your dog together with strangers, dogs you don't know. There could be a vicious dog in the mix, a scared dog, a dog who hasn't had vaccinations, a sick dog. The list goes on.
We love our dogs. They are family. But in the end, they are dogs. We don't speak their language, and we don't know what they are thinking. What's going to set off your dog or lead him to run and chase a cat on the other side of a busy street? We just don't know, and there's no surefire way to determine their next moves. If you love your dog, realize that a leash could save his life.
Find out more about your state's leash laws. You can always call your local humane society or police department for information or if you encounter an unleashed dog in your neighborhood.
