I may be overreacting, but here is the question....About 3 weeks ago Puddy (chocolate lab 19 months) bumbed her head on the stand when she raised up and there was a bump, almost like a knot at the crown of her head. It seemed to go away and then this past weekend I noticed it again. I do not recall her bumping her head. I have looked at pictures and I can not see that it was there before. This time it is not going down. It does not seem to be bothering her or in any pain. My husband says that I am obsessing over it. Should I call the vet or wait and do you think they will think I am crazy???
