how many dog breeds are there?

how long is a piece of string?

There are 209 recognised by the kennel club but there are loads more new breeds like labradoodles which havent been recognised yet

There are over 400 reported dog breeds in the entire world. The American Kennel Club recognizes about 210 of those.

It depends on what group of dog you are asking about there is are Spitz-type dogs,Hounds,Primative,Toys,Working/Herding etc but there are over a hundered in each group so it would be almost impossibel to answer that question

there is probably 300-400 true breeds of dog (I,m not including labrdoodles etc as these are basically crossbreeds)
