I suggest you contact the breed clubs asking for breeder details, and find a breeder your happy with, and get on their waiting list, expecting it to take at least 6+ months.

I would advise writing a full email giving details of household, dog owning experience, existing pets, and most importantly care arrangements for pup/dog while your not home, and kind of lifestyle and purpose.

I expect some breeders at the moment are getting many unsuitable enquiries, so some may be tempted to delete enquiries in frustration.

Do not be tempted by any litters where full hereditary health testing has not been carried out.

Just not worth the risk of potential pain and suffering (pissibly reduced longevity) for the dog, and heartbreak and not to mention cost down the line.
