I suggest contacting the breed clubs for a list of reputable breeders. No reputable breeder is likely to consider selling two pups as a puppy needs undivided attention and training for at leat 12 to 18 months. There are many disadvantages to ahving two pups or two close in age.
They are likely to bond more with each other than you and find it hard to cope wif parted.
Training will be three times as hard as you will need to trqain each seperately and together.
They will make 4 times the mishcief.
When mature there is a higher risk that they will fight for dominant postion.
they are likely to die close together, and often within weeks of loosing one due to grief.
