PetSmart is the world's largest pet supply and services retailer, offering over 10,000 products in stores and online to meet all of your pet's needs. The company provides a varied selection to cover the needs of dogs, cats, birds, fish, amphibians, reptiles, and several breeds of small animals. Customers can now shop online and pick up at their local PetSmart within two hours. Select store locations offer dog training, pet grooming, pet boarding, PetSmart Doggie Day Camp, and pet adoption services. Customers have had positive experiences with PetSmart, praising the store's fantastic selection of pet products, knowledgeable and helpful staff, and hassle-free return policy. The grooming services have also been well-received, though some customers noted the prices were higher than expected. PetSmart's aquarium and fish selection have been praised, with one customer's fish thriving after purchase. However, the store was sometimes unwilling to sell certain products, such as small algae water, to customers with smaller tanks, even when they planned to upgrade soon. Overall, PetSmart is described as a "hidden gem" with a great selection, helpful staff, and a convenient shopping experience.
