The most expensive dog breed in the world as of now is the Samoyed dog breed.
The Samoyed dog breed cost around $14,000.00 to $18,000.00 and sometimes more depending on the breeder you buy the Samoyed dog breed from.
There are other expensive dog breeds as well such as the Azawakh dog breed that costs around $9,500.00 and the Tibetan Mastiff dog that costs $10,000.00 the Chow Chow dog that costs $11,000.00 and the Lowchen dog breed that costs $12,000.00
But as of now the Samoyed tops the list at being the most expensive dog breed that you can buy.
Me personally although I love dogs there's no way I'd pay over $1,000.00 for a dog breed as that is a lot of money unless you're really rich and can actually afford to buy the expensive dog.
