I'm not going to judge conditions because for all I know that could be a shelter and a holding area. The tile floors look like something in an office building. I'm sure those dogs are getting taken care of.
Someone once told me when I had my first dog "You probably bought your puppy off a puppy mill breeder." I was like "No, I know what puppy mills are and this was no puppy mill." She kept insisting it was and it made me upset because she kept insisting without facts.
You don't have to feel the need to defend your video- the puppy saying elmo was cute as can be. However, rows of tiny crates filled with puppies of various breeds, shredded news paper on the floor, and noticeable filth are not ideal living conditions for a dog. It's not an assumption it's right there in the video and disturbing
