The Pueblo Petco has really impressed me. All of their employees are very friendly and helpful. I…read moream a dog and saltwater aquarium owner, so my experiences related directly to that.
First off, let's talk staffing. Their fish department is wonderful. Ron, one of the higher ups, knows his stuff, and will chat with you to figure out how to help. The female fish staff (I feel terrible I can't remember her name) is knowledgeable and works diligently to keep the live stock clean, fed, and disease free. She is well versed in SW care and if she doesn't know the answer, she finds it for you quickly. I've been looking at their aquariums over a year and I've never seen any noticeable disease.
As for dog stuff, when we got our second puppy, we needed a crate. The staffing, specially Joyce, was super friendly and helpful. We shared photos of our pup and they made me feel like they cared about everything I discussed with them.
As for stock and availability, I cannot say that I don't wish they had more, but for a big box store, they do have a variety of both aquarium and dog stock.
They do not carry too many corals, but do have candy cane, Kenya tree, a variety of zoas, and some leather corals. They do not currently stock macro algae. They sell Instant Ocean salt and reef salt, as well as basic products for water care. Unfortunately no reef master test kits.
The Pueblo Petco has a variety of dog stuff, much better than their major competitor.
With regard to store cleanliness, they are leaps and bounds ahead of their major local competitor. The store does not smell like urine, and all of their livestock have clean living quarters. I have personally witnessed an employee cleaning a rodent cage and taking a moment to pet and hand feed it treats. You can tell they are well cared for.
In review, wonderful, customer oriented staff, acceptable stocking, and above average cleanliness.
