Review on Small ThunderEase Anti-Anxiety Pheromone Collar For Calming Dogs by John Campos

I have purchased these collars each month for several months, hoping that over time they would become more effective. Problem is.they only keep getting more expensive, and they just don't work. Perhaps it's because my dog with separation anxiety is older and doesn't respond to a mother's pheromones? I don't know. But, I'm not wasting any more money on these. They haven't helped at all. In fact, she seems worse. The neighbors say she howls the whole time I'm gone, and that is something that has started since I starting using these.
