The best way to prevent your pet from getting lost is by ensuring they are always wearing a collar with an ID tag that includes your contact information. It's also a good idea to have your pet microchipped, as this can greatly increase the chances of them being returned to you if they are found. Additionally, keeping your pet in a secure and safe environment, such as a fenced yard or on a leash during walks, can help prevent them from wandering off. Regularly updating your pet's ID tag information and keeping recent photos of your pet on hand can also be helpful in case they do get lost.
