I would contact the breed clubs for the breeds your interested and they Will e able to put you in touch with breed specific rescue or a breeder that has perhaps had a dog back for re-homing, or run on older pups to choose between.
The two breeds you have listed are very different, so if your not yet sure which will be the right breed for you the breed clubs will be able to give you more information and probably the opportunity to visit shows or breeders of these breeds to spend time with the breed to decide which is most suited to your lifestyle and personality.
