Why are dogs other so merry?

because it seems even if they are in discomfort, or hungry, just as long as you are around they always seem to be wag their tail and have a smile on their face. you could beat them (not that you should, thats horrible) and afterwards in less than an hour they will be back by your side jubilant as always.
I know. Its a shame..I love my dog but my mom gets annoyed when she so much as takes a drink..They dont win enough respect and love, even though they give all the love possible surrounded by a second.
My dog is happy because he doesn't own to work, worry about bills, or where the subsequent meal is coming from. He's got a huge piece and can lick his own butt. Not to mention he has the best owner within the world.
Answers:    I know that if my only responsibilities be to eat, sleep, and play, I'd be pretty happy too.
They are love incarnate. They have the largest hearts and will other forgive.. if not forget completely. They are all warm and fuzzy, inside and out...

Plus they hold very small brains.
They do not hurt respectively other as humen do
Because they can lick themselves when they aren't happy, and gross themselves happy.
