After reading all the reviews here regarding puppy mills and Petland it makes me a bit sad. I have never bought a dog here, but I do shop here for pet related items such as dog food and dog treats.
Petland has a credit card you can acquire to use, which I have and which is why I sometimes go out of my way to buy dog food here. Sometimes they will run really good specials on dog food (I got a large bag of Science Diet for only $25.99). When you buy certain items here once you buy so many you get one free. Each time you purchase they will give you a receipt and tell you how many more items to go before you receive your free purchase.
Anytime I have gone in the staff is actually quite nice. There has never been a time I haven't been greeted or been asked if I needed help carrying my dog food out to my car. Unfortunate to hear about the puppy mill situation, but honestly, I am pretty aware of the fact that places like this get their dogs from mills. I'm not condoning it, but the 3-star rating is not based off of that fact, just my experiences in the store.
