So i want to breed my dog
 

How do i go around searching for a mate for him.

Newspaper ads only?

Im not even a dog owner but if I had an AKC registered dog I would check out the AKC website for info on locals in your area looking for stud service for that particular breed

As above, now you got me interested. A rottweiler would be nice.

Its fully registered has its pedigree and all that shit

thats my dog. Where do i find it a mate

Why do you want to breed your dog?

There are too many dogs in this world as it is. Majority of them are treated cruelly as well.

As Bob Barker says, "Control the pet population, have your pet spayed or neutered. G'bye everybody!"

I dont care what you think.

I want to breed my dog, there are too many people in the world, should we just stop having sex and reproducing?

Yes.

Millions of dogs (just as good as yours) are put to death every year because there aren't enough homes willing to take them. For every puppy you breed, another dog (just as good as yours) will die.
