Petco

They have a good rewards program and great sales. They also have a 30-​day guarantee on the fish, which is longer than most stores. They take good care of their tanks and fish, at least for a big chain store.
My experience with their customer service has been mixed. Some employees are helpful, knowledgeable, professional, and courteous. They have helped me out of a few jams.
Most of the time I have to wait a long time to be served. Sometimes the employees seem frazzled from and preoccupied with other duties.
One time, when returning dead fish, I was treated disrespectfully by an angry employee for not having a water sample (I had checked beforehand, and was told a sample was not needed). I was sent an online survey afterwards, and filled that out. After completing the survey, I got an automated reply that the store manager would contact me, and I have never been contacted. So, I now only shop there for «emergencies.» Hopefully YMMV.
Update 2÷25÷16: I got in touch with corporate customer relations through Petco’s Facebook page, and they responded right away. I got a call from the local store manager a day or so later, and I felt he listened to my concerns and took them seriously.

Both have bought plenty of salt water fish and continue to get my Cocker groomed there for years with no real issues. Staff is always helpful and I feel they do the very best they can.

I also had a horrible experience. I took my 6 month old GSD to get a bath and nails trimmed. When I picked him up he looked okay. Except they told me they couldn’t trim his nails because he didn’t like it. After I got home I notices he had something gummy stuck in his fur. It was at the base of his spine close to his tail. I tried washing it off with a wash cloth. I thought I had gotten most of it. Well I hadn’t. 2 days later we ended up at the vet because he had serious skin irritation. They ended up shaving 2 separate spots along his spine. He had a reaction to the shampoo that was left unrinsed on him. It’s been about 6 – 7 month his hair is finally grown back. I would highly recommend not using this place.

My mother so graciously took our two dogs to get bathed and groomed here last weekend. She has taken them here before to pretty good results. Apparently that was a fluke because both dogs came back with crazy haircuts. She requested that our malamute mix simply be bathed and thinned out from her winter coat. When she returned to picked the dogs up, she found the malamute shaved completely and looking like a sheered lamb. This was A) not asked for and B) completely insane to do to such a dog. She now looked like a bobblehead as her head apparently hadn’t been touched as neither did her tail. She looks liked a completely different dog. On seeing this my mother became hysterical and starting crying about what they did to the dog. Upon seeing this the two girls on duty that night that did this to the dog immediately started blaming her and when the manager came in he too blamed her and took the receipt from my mother as to I guess erase evidence she may have? They continued to blame my mom for what they did to my dog. On top of that, we discovered later on that the other dog had also been randomly shaved a randomly different length under his chin than he had everywhere else. I can understand MAYBE screwing up one dog, but both dogs? Are you kidding me? Needless to say the dogs won’t be going there anytime soon unless its for halloween.

Prices are higher than amazon for the most part. But they tend to have great deals on cat treats. Petco carries Dog Whisperer products. We bought two soft sided carriers there for our cats and all of us love them. Worth the money. And Petco had a nice selection of soft sided carriers.
