I use this on my dog who has become immune to the bitter apple spray. She licks lesions into her leg regularly, and I tried this. One word of advice - keep your mouth closed and do NOT inhale while spraying this. It has the most awful taste, and takes forever to get rid of. Scamp runs when she sees me coming with the spray bottle!

Pros: Dogs will avoid this

Cons: Lord help you if you breathe this in, it is noxious!

Works for some dogs, had one that just didn't care. You don't want to get on your hands though, it has a very offensive taste and it doesn't wash away easily.

Pros: effective

Cons: Don't get it on your hands, does not taste good!!
