I asked my friend who knows everything about animals...but she didn't know the answer to this. (Thanks for nothing TINA!! :)) I continued to ask people all day long and after I got a puzzled look from them, they too admitted that they didn't know.
My next step, Google of course. I got no answers there either. However, I did find that I'm not only one that has wondered about this. A lot of people posted their opinions on why dogs did this but no concrete answers.
For those of you who know me, you know very well that I love using the bathroom. I can't imagine having to run around and find the right place. I guess it's like when we (humans) have to go really bad and there is no bathroom in sight. Can you imagine feeling like that regularly? I would go crazy. I love my little Pepper and I wish I could make his bathroom experience easier for him. He doesn't seem to mind the search, but on mornings like today, when he is so eager to go, I wish there was something I could to do help.
Here I am hours later still answer less. I suppose I'll be making a trip to the library.
Stay tuned....
