Now is not a particularly good time to look for a puppy - BYBs have jumped in where 'reputable' breeders have curtailed their breeding plans because of Covid 19. And you'll find prices have gone through the roof although there are small signs of them coming down. I've also noticed many people with puppies of just under a year, realising they have taken on more than they can deal with, so these poor youngsters are looking for new homes. But still at inflated prices as people hope to get back what they paid for them.
Why not go back to whoever bred the previous dog - if they don't have any litter available, they may know of others who do. Also the relevant Breed Club may be able to help.
