I think I saw someone asking something similar a few days ago. As it stands currently, there is no option to wipe or delete your account.
You might be able to send in a support ticket to have your account wiped or locked if you wanted to start over on a new email, but the staff is a bit backed up right now with other things so I'm not sure how responsive they would be, or even how that process would go.
If you want to, you can try selling your current wolves for very cheap to get rid of them all fast, giving them away in the forums, or releasing them. As for your progrens, you can't really remake them, but you can risk randomizing their colors with a besprinkler from the Mole Market to try and get some new looks. And then you can sell or give away all your items to clear out your inventory. I know it's a lot of work, but like I said, I don't know that account wiping is something the staff really have the time to help with ATM, especially with an increase in people seeming to want the same thing.
