As I said at the beginning of this thread, the presence of dew claws in the United States has a high correlation to the lack of health testing, use of contracts, etc. That doesn't mean that in other countries it is the same. As for everyone saying that they are a "natural breed", it is not an uncommon practice in the Congo for basenjis to have their tails docked, so even in their country of origin, they are not always left unaltered.
