Adolescent Doberman and Fence Jumping

I have an 8 month old doberman who is starting to realize the 5ft chainlink fence isn't going to be an obstacle for long. She has good recall (for the most part, working on recall in distracting situation) and basic obedience. She gets daily training and plenty of exercise.

Lately she has been jumping on the corner of the fence, sometimes attempting to get over it. She hasn't made the jump yet, but will sit and study the fence after failed attempts. The only time she has an urge to attempt to get out is if there is a cat/small animal or I'm outside the fenced area.

I've debated starting e-collar training to fix this, I don't think she'd go far but don't want her getting hit by a car. Any advice for e-collar training or any other type to reduce this behavior would be greatly appreciated!
