I think all those dogs look super healthy and happy and have excellent living conditions. Show breeders do breed lots of dogs. This may be a bit more than usual but they have the space and, maybe, the time as well.
The dogs are looking...even posing for the camera. In the pics, you can see the dogs coming toward whomever is the photographer. These are happy, affectionate animals and look good.
It does seem a bit much at first, but I like their head-on approach on the website. This is what we do and how we do it!! "Puppy Mill" is thrown around a lot. Let's save it for someone who deserves it.
BTW, I like #3 girl. My brother had one just like her named, Abbey. She was his best friend for 15 long years.
