The Fourth of July is a day of festive celebrations, but it can take a frightening turn for pet owners.

Fireworks and other loud noises can spook animals and cause them to run away, and big parties with lots of people going in and out can mean its easier for cats and dogs to get loose. Thats why multiple animal shelters around the country say July 4 and 5 are some of their busiest days of the year as they take in lots of found animals and deal with panicked owners searching for lost pets.

Emily Weiss, vice president of shelter research and development at the American Society for the Prevention of Cruelty to Animals , noted that celebrations throughout the summer can be dangerous for pets.

The summer months are a busy time for shelters, as many pets are at an increased risk of escape during holiday celebrations because of the crowds, loud noises, and open doors and windows, she told HuffPost in an email. The most important thing you can do for your pet this holiday weekend is to be sure they have a visible ID tag with your up-to-date contact information.
