How many dog are there in the world?

Answer 1

There are a few hundred million dogs in the world, tens of millions as wild dogs. One estimate is 400 million, but no precise figure is available. (see the related link)
The American Kennel club recognises around 150 breeds of dog. There are, of course, other breeds bred specifically for the conditions of particular countries around the world, so there are more than 150 breeds in total. On top of that, there are another three dozen or so species within the dog family (canidae), such as the dingo and various wolves.

As for numbers of actual dogs in the world - that is impossible to determine, but hundreds of millions are put to death in shelters every year.
No one knows how many because on puppy mills they are born 24/7.

Another answer

The American Pet Products Manufacturers Association published they estimated a number of 77.5 million dog owners in the USA alone. The survey showed at least 25% of the dog owner had two dogs.

A third answer:

There are over 220 million dogs in the world.

their are over 2.5 billion dogs in the world to this day but i think in about 30 years their will be 3 billion. and in 2079 they will be only 1billion dogs in the world because we are getting to many people in the world now.

1.4 Billion dogs are worldwide. Go to an animal shelter and get a pet!!! Did you know that 800 dogs and cats are killed each HOUR???
Americans own approximately 73 million dogs in the world.
