my dog is only 7 weeks old. where his whiskers are it is all super bumpy and bleeding, plus on his lower lip it is now bald and bloody... now someone said salt on the ground since it is icy here. I put some salt down so the ice would go away. but i don't know if that's what it's from.. I have been cleaning it daily and putting vaseline on it. it is still bleeding and it's been about 3 days... does anyone know what this could be. he is still playful and has an appetite, but he whines when he is eating cause his mouth hurts. i would ask my vet but she is closed for the holidays....
