I was visiting some boarding kennels because I was planning on boarding my dog and one of them was Hay Hill Kennels on N. Washington Ave in Green Brook, NJ. The place was so dirty. There was a large dog in a small cage without even room to move, nevertheless go to the bathroom. It was during the summer and they only had a fan on and not air conditioning. The staff was completely rude and they did not look professional at all. It did not seem like they knew anything about caring for dogs. There were flies all over the place and dirty food bowls on the floor. The place was just a complete mess. It was such a huge disappointment.
