PetSmart is a large pet supply retailer offering a wide selection of products for many types of animals, along with services like grooming, dog training, and adoption. Reviews note that employees are generally helpful, friendly, and provide great customer service, with specific praise for assistance and grooming. However, some customers feel that employees need more information on dog behavior and boundaries. While the store usually has what is needed, some mention low stock on items and that the large store could offer more, leading to reliance on online shopping.
