I'm Sold!! This works!
We adopted a mastiff/lab mix about 6 months ago and didn't have a back story on the dog. It was obvious that he was never socialized with people or other animals. After we brought him home we found him to be aggressive towards other animals. Turns out he has hypothyroidism, so he's on meds for that so we then again tried to reintroduce the dogs to coexist in the house and you could feel his heart race when the other dog was near and he would get upset and anxious if you paid any attention to our other dog. After about a week of using this product once a day, he's fine, he's calm and just relaxed!! The dogs can be in the same room together with no issues at all! I haven't seen any adverse side effects either. I'm sold, please don't ever stop making this product!! :)
