Puppies Plus Rude horrible customer service only cares about money and not the animal Reno Nevada

i went into the store today 6-5-2014. I went there to look for a specific breed. They had one and I viewed it. First of all this poor puppy I was viewing was serverly dehydrated. I noticed that each station the animals where In had only one water container. This poor puppy drank so much that he threw up his water. They man took him away from me and said he wouldn't sell us the puppy because we let him run around in his filth. For one. the puppy isn't my responsibility and the man should have been watching over us with his puppy instead of trying to make a business deal. And for two he can not judge me for the short period of time I was there. He made me feel bad and mad. To be talked down and judged to that way. So this is my concern about this business. The poor animals are dehydrated. And confined into cages with multiple animals in them. And the poor puppy I was fewing was scared when I reached to pet him. The animals are scared and don't go near the owner. Is there anyone that can investigate this shop? Isn't this considered a puppy mill and aren't those outlawed?
