Well im not sure the dog was sick, but it was a large dog that seemed to have trouble moving his back legs.. They had to put a sling around his middle, and 3 women got him out to the car.. Thats when I had the chance to observe the assistant.. I did speak the the groomer alone about what I observed, She said they had to keep the dogs quiet because another store at the mall complained about the noise. But it certainly did look like she was making them bark so she could hit the side of the cage... I stood there at least 5 minutes and never say her speak to any of the dogs . She just looked and acted mean .
