The grooming is horrible. I've been there several times and service was always underwhelming. The last time I went there, it took forever (though we were promised 3 hours, it took 6 hours on a Saturday) and when my dog came back home I noticed fresh razor cuts on his stomach. I will never go there for grooming again.
edit: I pass by this Petsmart all the time because it is in the same strip mall as my grocery and Michaels. One night after shopping at Michaels (about 5pm) I was walking to my car in the parking lot and noticed a large dog running from the direction of this Petsmart to the Hash House a gogo across the parking lot. I tried whistling to it but it just stood there staring at me. It was too far for me to see what breed, but I think it must have been a black lab or a dark larger dog, and looked clean enough to not be a stray. I ran into the Petsmart and alerted their grooming department and Petshotel in case they were missing a dog. They had no idea if it was one of theirs but two of their associates came out with me to try to find it. It was getting dark and I had to leave but I never did find out if they got the dog or what happened to it. But ever since then I will NEVER EVER board or groom my dog there. I pray that it wasn't one of their customers dog. Can you imagine being a pet owner and going back into the store for them to say that your dog has run away into the night?
