Hi Audray, thanks so much for your honest review. Border Collies are smart pups and generally way ahead of the curve when it comes to thinking about what's coming their way. Our English Springer (Bailey, who's the namesake of the No More Wiggles) tends to pant the moment he hears thunder or a bang, whereas our English Cream Retriever (Harper) is as dumb as a rock (but lovely) and seems to start stressing herself out for events she knows are coming.
Once the stress response gets going, there's pretty much nothing you can do to bring the dog back to calm. Preparation will help - with travel you might be able to give more an hour before alongside just sitting in the car with the dogs and reading a book while they get used to just being in the car. We have to do this with Harper and she's calmed down, and she's finally started to calm down although that might just be because she's older?
I can also say that Lilly (one of our resident experts) says our topper makes a huge impact on her nervous dog even though it doesn't have any CBD (although she notes "I just have to mix the topper with green tripe to get her to eat it lol").
