When we came for the four hour orientation, our 4 month old puppy seemed to love it. However, the following day when I dropped him off for a full day, he whined when they took him in the back. THAT SHOULD HAVE BEEN MY FIRST SIGN. When I picked him up after work, he was acting really weird. He wouldn't play. Wouldn't touch his food. Kept crawling in our laps and whining. He also smelled very strongly of urine! Everything he touched smelled like urine. I had to bath him and everything he laid on before we went to bed. The next day he wouldn't eat and threw up all over the place. I don't know if they fed him the wrong food, gave him a bad treat, or if he got sick from another dog. Whatever the cause, he will never be going back!
