Insider Reviews has been evaluating pet products for the last four years, testing hundreds of toys and accessories with our own pets. Our reporters are experts in the field who have worked as dog trainers, studied veterinary science, and assisted in vet offices. Through our reporting, we’ve also spoken to numerous veterinarians, animal behaviorists, dog trainers, pet safety experts, and devoted pet owners to guide us in our recommendations for products that offer the best quality, value, and safety.
What types of pet products we cover
Food: After hundreds of hours of interviews and research, we carefully selected the best cat and dog food. All of our picks were guided by animal nutritionists and veterinarians. We’ve also tested some of the most popular fresh dog food, including The Farmer’s Dog, Just Food for Dogs, and Ollie.
Health and wellness: There is an overwhelming number of flea treatments and dewormers on the market, but not all are equal. Our reporter consulted veterinarians to find the safest and most effective options for cats and dogs. Read more about them in our guides to dog flea and tick medicines, cat flea treatments, cat dewormers, and dog dewormers. And if you’re in a pinch and need some advice, we’ve also researched the best online vet services.
Harnesses: Some dogs pull on leash; others walk nicely but need a harness that will hold up to rugged outdoor adventures. Our reporters tested harnesses with untrained shelter dogs and drew from two decades of combined experience as professional dog trainers to bring you the best harnesses and no-pull dog harnesses. And because cats can walk on leash, too, we spoke to adventure cat parents to find out what harnesses they use with their cats.
Grooming: Regular grooming and dental care are a pet parent’s most challenging — and least enjoyable — responsibilities. We’ve tested dog nail clippers and grinders, dog toothpaste, cat dental products, and brushes for dogs and cats. Veterinarians and professional groomers also helped us narrow down the best regular and medicated dog shampoos and at-home dog grooming products.
Toys: When it comes to keeping our pets happy and healthy, toys are a big part of the equation. But not every cat or dog will appreciate the same puzzles, balls, or scratchers. That’s why we’ve tested dozens of cat toys and talked to animal behaviorists, dog trainers, and pet parents about their favorite toys for dogs and rabbits.
Travel gear: To keep your pets comfortable and safe while traveling, we tested 30 pet carriers for our guides to the best cat carriers for everyday use and air travel. If you’re looking to hit the road with your dog, check out our roundup of road trip must-haves with tips from pet safety experts.
Outdoors: Because pet parents spend a lot of time outdoors with their dogs — on land and water — we’ve covered hiking gear, dog life jackets, boots, snow coats, and rain jackets. We didn’t forget about cats, though.
Pet training and behavior: Whether you’re bringing home a new pet or want to teach an old dog new tricks, our reporter who is a professional dog trainer can help you choose a dog muzzle, protect furniture from cat scratching, introduce a new cat and dog, potty train a puppy, train a dog, calm an anxious dog, prevent separation anxiety, and keep kids safe around pets.
How we evaluate and test products
We approach every article with pet safety and wellness in front of mind. Our testing methodology and product selection criteria are informed by interviews with impartial experts, including veterinarians and animal behaviorists. We devise tests to ensure our recommendations are easy to use, hold up to wear and tear, and keep our pets happy.
When we can’t lab test products like flea and tick medications and pet food, we head straight to our experts and consult industry standards from organizations like the World Small Animal Association and the Association of American Feed Control Officials to rigorously evaluate options. Our guides are then vetted by impartial medical reviewers who are licensed veterinarians.
