Customers have praised PetSmart's excellent customer service and grooming services. One customer was impressed that the groomers were able to trim their old and grumpy dog's nails without using a muzzle, and the process was quick and stress-free for the pet. Another customer found the Blue Buffalo representative, Paula, to be very helpful in finding a suitable dog food for their senior Chihuahua with poultry allergies. Customers also appreciate PetSmart's flexible return policy on pet products, which allows them to return unused items.
