We adopted Rogan 2 years ago from a rescue in AZ. He had some trust issues with people, probably due to a broken jaw that, even after surgery, did not heal. He could only eat very small morsels of food and would yawn and the pain was so bad he would turn his head to accommodate and end up doing a u-turn in mid stride. I started him on these immediately and we noticed gradual changes to the point that he was able to chew on small bones for a short period of time – so it helped the pain enough to enable us to work to strengthen his jaw.
It’s still permanently crooked, but he no longer cringes in pain when he yawns, he chews bones, and we say “he’s now a real dog doing real dog things.” I know it’s in large to your products.
