I've started runin a 11 month old pup with the grown dogs I've ran her with them 2 times and here pads on all four feet are gone and bleeds what is the best stuff to build the pads back I've tryed a few thing but no sing of getin better

That all depends on your situation. If she has been running for a while and is tearing her feet up that bad you should give her away and save yourself lots of work. You can try rinsing them off with some hydrogen peroxide to clean them. Let that dry and spray Granulex V on them for a day or two and then start putting some tuff foot on them every day for a week or so. If your pens are dirt you will have to wrap them with vet wrap to keep dirt out. If you have concrete just wait until each pad dries when you put the medicine on and they will be fine. That should help.
