Your dog can teach you a lot about life.  For instance:

Take plenty of walks and naps.

Drink lots of water.

Don’t think too much.

Make friends with everyone in the neighborhood.

Don’t go for a run without your ID.

Make the people you love feel welcomed when they come home.

Every now and then, stand out in the rain.

Why do some men have a dog and no wife? Here are some possible explanations.

The later you are, the more excited your dogs are to see you.

Dogs don’t notice if you call them by another dog’s name.

Dogs like it if you leave a lot of things on the floor.

A dog’s parents never visit.

Dogs agree that you have to raise your voice to get your point across.

Dogs find you amusing when you’re drunk.

Dogs like to go hunting and fishing.

A dog will not wake you up at night to ask, “If I died, would you get another dog?”

If a dog has babies, you can put an ad in the paper and give them away.

A dog will let you put a studded collar on it without calling you a pervert.

If a dog smells another dog on you, they don’t get mad. They just think it’s interesting.

If a dog leaves, it won’t take half of your stuff.

 
To test this theory, lock your wife and your dog in the garage for an hour. Then open it and see who’s happy to see you.
