Most people that have many litters in a single year are not doing it the "right way". Since most basenjis only come into season once a year, that means most litters are born within a very narrow window of time. It is a lot of work to properly raise a litter so it gets the socialization and attention they need to become well adjusted adults. Breeders who have many litters at the same time would be hard pressed to give each pup the individual attention that they need.
I don't think that anyone was trying to imply that your puppy wasn't "up to standards with you people", but were trying to say that your pup's breeder may not be the best source of information.
A responsible breeder, one that is doing it the right way, is a great resource for their puppy people. They keep in touch with them through the life of their dog and provide information on the health of the pup's relatives, on feeding, training, and helping the pup adjust to life in its new home. They are there when you have questions or need help. They will take back their puppies at any age for any reason or no reason at all. Usually, the breeder has already established a relationship with their buyers before the pups go to their home so when questions arise the lines of communication are open.
From your posts, I think people may have gotten the impression that you did not feel comfortable about contacting the breeder. You cited that your pup had a skin infection when you brought her home as one reason you did not trust the breeder. This may be why people may feel your pup's breeder may not be a "responsible breeder".
