My 6 month old, 48 pound Lab/Boxer mix had adverse reactions with this product. He almost immediately began pacing around in circles, acted restless, and was panting heavily with his mouth closed. After a few hours of this and trying to figure out what was wrong with him, I thoroughly washed him and he seems to be okay now. I am calling my vet tomorrow to see what other products are available. I do not trust using this product again. I had previously used up the 21-55 lb. package and purchased the next level up because he is still growing. He acted a little funny after each of those applications but it was nothing like he acted after the first time using the 56-95 lb. dose that I applied today.View Thread
