Tina Higdon answered question 8/24/2009 My Dog Has Chewed His Hind End To Raw Skin And Bleeding. Im Giving Him Benadryl But He Wont Stop. Now He Is Acting So Strange And All He Wants To Do Is Lay Outside? I've never heard of a dog doing that if theyhave parvo. It sounds like it just has a bad case of allergies and just needs a shot to calm done the itching. Thats the most common thing that dogs get when they are itching
