Also if it doesn`t drop while a young puppy at several weeks of age, what makes it drop at an older age. Is it a weakness specifically in the jaw area or a bone type condition that can end up anywhere but settling in the jaw most of the time? I hope this is not a stupid question!
Not stupid at all!! For me, wry mouth is a hard one to wrap my head around until it was explained to me like this, (and this is how I understand it) and I'm still learning:
Wry mouth really has little to do with the actual "mouth" (or tooth placement). It is actually a malformation of the entire jaw, and sometimes even the skull. Wry mouth can be anything from a twisting of the lower mandible (you will notice that the canine tooth will twist downward almost always on the dog's right side) to the actual joint of where the mandible connects to the skull being slightly off. This is why wry mouth can be such a hard thing to correct/breed out. First, it can be hard to tell exactly why or where the problem is happening (i.e. - what part of the head needs "correcting"??) Second, since it is more of a malformation, it can happen to a slight degree. Because a bitch (for example) can be ever so slightly wry, you may not notice it, and when bred to a dog that has wry mouth behind him, her pups will inherit the horrible mouths.
Keep in mind how much puppies heads change even through the age of 2 years old. Puppies generally go from looking like parrots, to the conehead stage, to looking somewhat like miniature boxers (at the age of 8 weeks, still retaining the conehead), to the dane faced stage (muzzles slope downwards), to the age that the muzzle starts to break over and the nose turns up. Even throughout the second year, heads will change and get wider, flews will drop, and eyes will tighten back up. Given how much they change throughout the first two years, it is quite possible for wry mouth to not show up well into the 6 month, and I would be surprised if it doesn't get worse from then until the head stops changing completely.
Having said this, I have also heard that wry mouth is a fairly common condition in not just boxers, but dogs in general. There are a few very good links out there concerning wry mouth. Doing a search on google should pull a few up.
