1) Life is all about play time. Play time should only be interrupted for occasional musts like sleep, food, and potty breaks. In fact, potty breaks should be put off as long as possible during play time. Oops, did I do that?
2) Accidents happen. When they do it is best to look very sorry and then snuggle up to whoever seems the most upset by them.
3) Sleep can occur at any given moment and should never be confined strictly to human sleep times. When you need sleep it is best to find a seriously comfortable place. I highly recommend crashing on top of the nearest human.
4) If at first you don't succeed in making friends, try, try again. The power of cuddling is always your greatest asset. However, this seems to work better on humans than on other dogs. Frankly, I'm still trying to figure out the whole making friends with other dogs thing. I've opted to forgo friendship with cats all together. I highly recommend giving them a very wide berth at all times.
I hope these lessons will be useful to you all! Now, I have to be going. Play time is here!
