If you have a 26lb dog receiving a pill for 26-50lb dogs, not only are you giving them double the necessary dose of neurotoxins and pesticides, but you are giving them an *entire months* worth up front.

You may need a tetanus jab (vaccine) if the injury has broken your skin and your tetanus vaccinations aren't up to date. Tetanus is a serious condition.

These bacteria can enter your body through a wound or cut in your skin.
