Hi!
I'm really sorry but without leaves, they're no life.
You must grab new seeds, start again and keep your dog away your little garden (it may be a good idea to have a closed space, like grow tent inside or a mini-greenhouse outside).
If you worried about your dog, don't be, he's gonna be fine : your plant looks very young (few days ?) and psychoactives appears later. ;)
"For one zillion dollar, the question is : who let the dogs out ?"
