i want to puchase a dog puppy asap please

Puppies take time to grow LOL so asap is unlikely.

Contact the breed clubs for the WFT listed on this site (click on breeders at the top of this page and then go to the breed and then clubs) and get onto the waiting list of a reputable breeder who may be planning a litter.  If your really lucky there may just be a puppy unreserved from a litter.  I would advise checking out the breeder's reputation with a breed club for any advert you see elsewhere.
