a st bernard jump two fences into our yard while my kids were outside taking my eight week old puppy out to go to the bathroom, and attacked my puupy. ( he didn't get hurt ) i had tograb the leash and throw him inside my house to get him away from the st. bernard. two days after this, my puppy has started to urinate on himself in his sleep. (not all the time) could this be caused from the attack or is this normal? and what would you recommend doing that might help my puupy?
