My wife breeds champion show dogs. To give you an idea check out
www.houseofwags.com That's my wife's web site.
ALL of her breeding dogs are champions. All of the puppies are raised in the home. All of them are played with every day, sometimes to the detriment of other things!
This looks like a potentially very bad thing for the puppies in the photo. No way on God's green planet would my wife, or any of her associates allow puppies to be in a cage on a grate. The grating is used to allow the poop and the urine to fall through, so the "keeper" doesn't have to clean up, after the puppies. Puppies that age should be in an exercise pen, not in a cage. A puppy who has lived in a cage like that for six to nine months may never learn to walk correctly, will have both social development problems and will have health problems with their hips later in life.
Let me put it this way: To me the photo looks suspiciously like a puppy mill.
this is very sad for the puppies--and it makes all dog breeders look bad.
