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 praise the helpfulness and friendliness of the retail staff, especially in the grooming department. The grooming services are described as professional and caring, with one customer highlighting the excellent work of a groomer named Brielle. While the pet training classes are excellent, some customers note that the puppy classes are overcrowded, and wish for more space to accommodate larger groups. Overall, customers are generally satisfied with the wide range of products and services offered by PetSmart, though one customer did note some issues with the fish area, where they observed several dead fish that seemed to have been there for more than a day.
