Little Tree, Big Leaves.

Out in the dogs' fenced in backyard, there have been a few new trees sprouting up.  The reason is that I have not mowed or cut anything out there for quite some time.  A couple of them have some large, unusual leaves.  The unusual part is that not all the leaves are shaped the same.  You know, like you know that all the leaves from an oak tree look very similar, just as maple leaves all look the same.  So, these leaves on this plant decided to be different, I guess.  The leaves are not small.  I would estimate that some of them reach 7 or 8 inches long.  And, before you ask, yes I did take two pictures of them and here they are:

As you can see from the above pictures, the ones out on the end have a smoother shape and the further back the stem you go the more scalloped the shapes become.  Some of the leaves resemble grape leaves.  If any of you have any idea what it is, please let me know.

Another unusual thing was that when I was leaving the dogs out, I saw a huge white dog on my deck next to my screened in porch.  It was all white and huge.  Seemed very mild mannered.  I believe that it was a Great Pyrenees.  It looked at me, turned, and slowly walked away.  It sure was a beautiful dog and I wonder where it lives.  Now, you all have a great day, you hear?
