Our rescue Astro came from a traumatic background with severe anxiety and trust issues. After a couple of weeks on DogZen, he's not aggressive in the mornings and actually sleeping through the night.

Two rescue dogs with severe separation anxiety and nervous biting. We tried every vet recommended brand out there. DogZen is the only one where we can actually see a difference. One chew makes sure that Jenny never bites

We got this for our old dog who just recently developed aggression issues in the evenings. One chew around 7pm and she no longer bites or barks. It takes the edge off in the best possible way. Best thing we have tried for her.
