Unfortunately we can't extend the trial period. You see, all the billing happens through ClickBank, and we don't have any control over their credit card system (for obvious security reasons).
If you really need more time for a trial, then I would suggest you cancel this subscription and start a new trial for 3 days. It will cost you $1, but I'm sure it's worth it.
To cancel your account at any time, please follow these cancelation instructions: https://theonlinedogtrainer.freshdesk.com/support/solutions/articles/5000537468-cancel-your-membership-yourself
Hoping you have a great training day!
