And ps.. its the higher concentration levels and longer time in the body that concern me. If the dog had a reaction it does not clear the body rapidly like Ivermectin does. That’s one of the reasons I would not use the injection. If I recall, the dogs that were dying from it were doing so after the second injection. This in my mind and opinion means it was not exiting the body quickly enough and building up in the system.
