The Difference Between "Normal" and "Common"
I seem to run into this a lot...People with a dog that has a medical condition. The people then tell me that this condition is "normal" for their breed of dog. I always tell them that use because something occurs commonly, that does not make it normal.
Take, for example, today. I'm examining a Chihuahua. I noticed two things immediately. First, the dog is not trying to bite me. (While this is normal for dogs, it's not common for Chihuahuas.) Secondly, the dog has an open fontanelle that I can stick my thumb in. I mentioned this to the owner, and she said "Oh, I know. All of my Chihuahuas have had that. It's normal for them." No, it's not. It's NOT normal. In fact, I will list it in the record under "Abnormal Findings". I will grant you that it's common.
