My dog has separation anxiety, and my neighbors are getting fed up with the constant barking when we're away. I'm worried that our landlord will make us find a new home for her, so we're ready to try anything. This didn't work. It seems to annoy her at least a little, but for the most part, the anxiety seems too powerful for the collar. I get home, and the entire house smells like citronella. I watch her through the closet door, and she just paces and barks. The citronella seems to make her hesitate a little at the beginning, but when enough time passes, she's just barkzilla. I'm going to try the Thundershirt next in combination with medication from my vet and maybe the bark collar. Wish us luck!
