While it is good that you are reassured - I'm not sure I would be at all happy tbh; commercial breeders are exploiting animals for their own financial gain, after all
More important though, did you see any form of certificates relating to health screening of the sire and dam? Just because the dam has clear eyes doesn't mean she isn't a carrier of PRA, and if the sire is as well, then the pups could go blind early in life
If the puppies are kennelled, and don't spend much time inside, then you may find it harder to settle your pup at home with everyday noises like the washing machine; Molo and his litter were born and brought up in a corner the breeders kitchen, so he curled up and went to sleep when he heard the spin cycle of our machine for the first time
I think any pup would prefer to be one of the family, especially as their litter mates leave, rather than being housed in kennels outside
Molo was the last pup to go, and he spent a week curled up on the sofa every evening with the breeder and her hubby
