Clematis Wilt

Clematis Wilt

Can clematis wilt occur so early in the season? One of my vines just started drooping yesterday and it's affecting the entire thing, down to the ground. Should I hack it off now and save the rest of the plant? There is also the mitigating factor that a month ago, my dog stepped on the clematis' feet and seemed to have snapped a bit of it below the dirt. It has, however, been fine since-- until yesterday. And, there is another vine coming from the same source as the wilty one, and vine 2 is doing perfectly well.
