There is no cool dog, why do you always send me text messages for verification?

I haven't downloaded it. Cool dog has been texting me for verification.

This is mainly because when using cool dog, you need to log in to your personal account or register. When you register a cool dog account, he will send a verification code to your filled-in mobile phone number, so that you can receive this verification code when you register your account. Thank you very much for your question. I sincerely hope that my answer can help you to some extent.
