I have played w3 and thus first thing I did in w4 was I have blocked fox with fence and he broke the fence and killed me (well K.O.ed me) so don't try to play whatever you play. FOX break FENCES (exclamation mark). No doubt about it. If he did not break the fence to you, you are just lucky.
BTW: Animals dont break sutff if they are trying to run from you... maybe that is the case. But careful, if they turn around and chase you back, they break stuff again, even though their icon is showing the peace-branch. I lost two LCs and several boats because of this.
