Katie. I'm not sure about that. But for those that are concerned why not try it. Not illegal and only costs a few dollars. I'm going to get one to see if I can train my neighbors dogs not to bark at me. Heck. I've only lived behind them for 16 years. Of course might not be the same dogs but it's the same owners.

A fish and a bird can fall in love, but where will they build their nest?
