Reincarnated

I always thought it was impossible for a person to reincarnate but I learned that they can.
After I died, I reincarnated but I didn't come back to life as a man.
I came back to life as a dog and my wife is my owner.
Even though I'm a dog, she still gives me a boner.
I was shocked when I looked in the mirror and saw that I'm a Saint Bernard.
Some times my wife tries to date men but I chase them and I bite them hard.
When I was a Human, I had elegance and class.
But last night I bit a chunk out of a man's ass.
Certain things put me in a bad mood.
One of which is having to eat Dog Food.
Being near my wife is intoxicating and it's sure to please.
But I'm about to itch to death because of these damn fleas.
I'll stop my wife from dating men until I die, that's what I'll do.
If you ever try to date my wife, I'll take a big chunk out of you.
