Tail

So my mother and I were convinced a little while back that my dogs dail was broken or pulled out of her socket...but it wasn't. I guess it was kind of ridiculous to think that she pulled her tail out of it's socket...is there even a socket to pull it out of? I think that is just an expression. In any case her tail is looking fine. My mom thought that it was looking a little too long - so silly I know!!
