hello, I just purchased a 9 week old jack russell pup. His ears do not flop over into a triangle like i have seen in pics. They do flop, but only a little bit. The ears kind of go back a litle bit, then flop down about a half an inch. I was just wondering if this would change with age, and if some jrt ears do not always flop totally down in the shape of a triangle?

thanks
