I got one of these for my newly adopted dog, who seems to have a bit of separation anxiety. I put it on her this morning and she's still showing signs of anxiety. I'm not sure if it takes a while to kick or if it's just not working. My trainer at my obedience class with my other dog told us about the DAP stuff she uses with her dog and that it seems to work well, so I gave this a try. I realize I probably need to actually address the anxiety issue with actual training and not just a drugged up collar, but at least it smells really good! It's like an air freshener for the house since she runs all over the place.

Pros: Smells good

Cons: Not sure if it works yet
