Issue with Neighbor over Fence

[Joel S.]

I just bought my first property about 3 months ago and am having my first issue. On one side of the property the fence is in pretty bad condition. The neighbor on that side just got a Rotweiler dog and it ended up getting through the fence and corning my tenant's wife. Bottom line is the fence needs to be repaired. We talked to the neighbor and he is refusing to split the cost to repair the fence which I think is more than fair. Is there anything I can do or do I have to bite the bullet on this one?
