I have taken my pets to your Petco locations in Shrewsbury and Auburn locations for many years. On Saturday 07/20, I had a very bad experiance at your Auburn location. My Samoyed is 13 years old. The technician was trying to draw blood from his right leg and he yelped, she reattempted it and the same thing happened. I was very upset and asked her why she did that and her response was that she could not find the vein. I feel that she should be more compassionate with a senior dog. He was slightly lethargic for about 2 days after this and I had to give him Rymadil for his arthritis. I did complain to the supervisor. I just want to let you know that I will not be bringing my pets to you anymore in the future.
