hi! i have a 1week old shih tzu he's healthy but my little brother accidentally stepped on its head :( after that i checked on him and i am sure he's in pain. he has now a soft spot on his head, like a part of its skull got cracked and some of a part of its brain got lump a soft lump on its head. is it going to heal? or any cure for it? my poor puppy is just 1week old and suffering in pain :( hope you guys can help! godbless! :(
