Thank you for trying to help reunite the pet you found. The best way to help this pet get reunited with their family is to create an account, and add them as a found pet.
Once the pet has been added under your account as found, you will see them listed on your dashboard under Pets. Select the Found Pet you would like to run a search for. You will then want to click the purple button that says Search. Immediately a search will be conducted and possible matches will appear for you to look through.
If you find a potential match, you can select the image and contact the pet parent.
