I agree with Hotel4dogs. The dad is should not be a dad yet.
With the mom personally 7 is the tops I would even consider breeding a girl and I personally do not like to see girls have more than five litters but preferably four or less.
Seven years and seven litters sound like a puppy making machine. If they waited til she was two to start breeding her, which is doubtfull because the dad is too young, she would have had a litter every year of her adult life and most years two. That is a lot to ask of a girl.
Normally when a reputable breeder is breeding a girl in this age range, it is because she has spent a good chunk of her adult life competing in the breed ring, obiedience, field, etc.
My main consern would be the lack of clearences. You want a puppy to be with you and healthy as long as possible, hopefully for 14+ years. Take your time, find a reputable breeder who does the core 4 clearences and then double check them online at Orthopedic Foundation for Animals
. There are several stickies at the top of this section that are very helpful.
When you do narrow down your search, provide the dam and sire names and we would be glad to double check the clearances with you.
