No, the tail size is written in the DNA. But if you neutered the dogs with long tails, and only bred the short-tailed ones, after a few generations, they would all have short tails. If you tried to breed them for shorter and shorter tails, eventually they would have no tail.
All dogs are the same species -- even the chihuahua and the great dane. They've simply been bred for specific purposes for a few hundred years. But if the dane has sex with the huahua, they will have a litter of dogs.
