Gracie was, hands-down, my most challenging pup.She is extremely high energy as are most collies but she was “all over the place” in terms of focus and concentration. She resource guarded, destroyed anything she could get hold of, plagued the other pets. She had no bite inhibition, impulse control or frustration tolerance. My sense is that most of these behaviours were learned, but that if I could just get her focus, I could train her. She’s also a sweet goofy, happy girl who’s eager to please. I shed buckets of tears as I couldn’t seem to get through to her. In desperation and hope, I ordered a bottle of Untamed Calm. From the third day, Gracie’s behaviour changed perceptibly. She’s still a goofy, intelligent, high energy collie (which I love), but now she can focus long enough for training to be benefit. Calm has made a huge difference. Training is going well, and she’s officially a member of the family and I couldn’t be happier. Thank you for your wonderful product. Kim
