I honestly don't believe many people would consider it so deeply, and if she did bring up that question I don't see anything suspicious in saying that this is the first time you thought of it. My understanding is that his dogs have only been mature a year or two at most. The people of the world are not on high alert, carefully examining every individual to see if they are a zoophile. Most folks never even think about it.I also agree with this but find it might be a little suspicious to her that his dogs have been sexual mature for a long time...and yet, it's only now he's worried about them being sexual frustrated/in need of release? If she brought that up, the only option is to admit you've been pleasing them yourself up until now, or sound like a jackass saying you've never noticed or thought of it before.
Simply put, raising this idea once is not nearly enough to raise any serious suspicions unless his wife is an ardent member of some anti-zoo group. I'll grant that he really ought to have talked about this before getting married, but there's no use crying over spilled milk. The best he can do now is carefully feel her out, and yes, abandon the idea of ever telling her if it seems like she could not accept such a thing. But before giving up all hope, an effort should be made.
