We have used that before, the sentry brand that emits the lavender chamomile spray. Lilah has also developed some issues with other dogs (since she was attacked in July 2014) particularly larger dogs. It is hard for me to find safe opportunities to try out appropriate interactions where she will be able to be kept safe and I can focus on correction of her intense behavior rather than protecting her from another dog- especially since her presentation is at least defensive if not offensive these days- so unfortunately I don't think I have much of a review to offer, we have pretty limited experience actually getting to use it! I'm really glad it is helping you. We have a close buddy maltese we play with

and Lilah is getting pretty good at just ignoring like, at the vet etc. a work in progress always I suppose!! I wish you the best
