PetSmart Pet Supply

Off Fourth Street in Ontario, our Accredited Trainers help puppies and adult dogs build skills that hold up in daily life. Positive reinforcement anchors every session, from group classes where dogs practice cues among real distractions to private classes shaped around your dog's unique needs, and special savings packages carry that progress across multiple courses. When you travel, PetsHotel near The Resort Pkwy gives pets a safe place to stay, with Standard Guest Rooms for dogs and Private Suites or Kitty Cottages for cats. Safety-certified Day Camp Counselors keep Doggie Day Camp moving with supervised play and exercise. Academy-trained Pet Stylists put over 800 hours of hands-on experience into baths, full grooms, haircuts, and a de-shedding treatment that reduces flying fur, with walk-ins for pet grooming in Ontario. Anything you order online can be picked up curbside when you pull in. Whatever the season calls for, coat care, cold-weather gear, or summer basics, it's stocked and waiting on our shelves. Adoptable cats and kittens stay with us through PetSmart Charities until the right family walks in. From boarding to grooming to training, every pet in your household is covered.
