I have an 7 week old puppy and we are trying to potty train him and he doesnt seem to listen... we have puppy pads in the house and we take him outside and whenever we let him back in he uses it inside and does anyone know how to make pups nicer? I believe his teething is what is making him so aggressive... I  think he will grow out of it but does anyone have any tips we can use?
