I've only heard good things about this breeder, I would not worry too much.
As far as over breeding the dog...you have to take many things into consideration...how many pups did the dam have in each litter. If she only had very tiny litters or only a singleton...breeders will breed the bitch more often.
If she only had a pup or two...the bitch bounces back very quickly...it's the large litters that can be harder on them.

Many breeders breed once a year for two or 3 years...or even a year or two longer if the litters were small...and then retire the bitch at the age of 5 or 6.
It's often recommended to breed bitches more frequently...and then retire them, because going through heats is so hard on their reproductive system.

I guess it depends on the breeder and the health of their bitch.
