Well first time for a non-well-health check up. She hit her nose on a display at Petsmart while rough housing with another puppy two weeks ago and I noticed a big knot on the top of her nose. Well Two weeks later and it has not gotten any better so kinda worried. If it is just a hematoma, does it take longer for the top of a dogs muzzle to heal???? It has definetly not slowed her down the least bit.
