Pet supplies is one of the most honest best-seller lists on Amazon. Nobody buys poop bags twice because of clever marketing — they buy them again because the last box worked. We pulled Amazon’s Pet Supplies best sellers on August 17, 2026 and picked ten worth knowing about, from $12.79 to $36.97.
The review volume in this category is unlike anything else we have covered: three of these picks have more than 120,000 ratings, and one is past 249,000. When a $14.99 box of poop bags holds 4.8 stars across a quarter of a million reviews, there is nothing left to guess about.
This is a best-of list, not a deals list — these are consumables at steady prices, ranked by how well they sell and how well they are reviewed. If you want percentages off, our Home & Kitchen deals roundup is the page for that.
1. Amazon Basics Puppy Pee Pads — category #1
$18.99 — 4.4★ / 221,137 ratings — #1 best seller in Pet Supplies
The best-selling pet product on Amazon, with 221,137 ratings. Training pads are one of those categories where the own-brand version genuinely competes, because the job is simple: absorb, do not leak, do not shift around.
4.4 stars is the joint-lowest rating in this roundup, and the reviews explain why: pad size and absorbency vary by the pack you order, and people who buy the regular size for a large dog are disappointed. Check the dimensions against your dog rather than the picture. These are for puppies in training, senior dogs and crate liners — not a substitute for going outside.
2. Dr. Elsey’s Ultra Unscented Clumping Cat Litter, 40 lb — $22.99
$22.99 — 4.4★ / 69,801 ratings — #2 best seller
The litter that vets and cat behaviourists recommend when a cat starts refusing its box. Unscented is the whole point: cats have a far better sense of smell than we do, and the floral perfumes added to most litters are a common reason a cat decides to go on the rug instead.
It clumps hard, which makes scooping fast and keeps the box usable longer between full changes. Two honest drawbacks, both in the reviews: 40 lb is genuinely heavy to carry and pour, and clay litter tracks — you will find granules outside the box. A mat underneath handles most of that.
3. Fancy Feast Gravy Lovers Wet Cat Food, 24-Pack — $22.86
$22.86 — 4.7★ / 55,152 ratings — #3 best seller
Under a dollar a can for wet food a fussy cat will actually eat. That is the entire proposition, and 55,152 ratings at 4.7 stars say it holds up.
Wet food matters more than most owners realise — cats evolved to get most of their water from prey and are chronically prone to under-drinking, which is a factor in urinary and kidney problems. Adding wet food to a dry diet is one of the cheapest useful things you can do. The gravy formulas are lower in protein than the pâté versions, so treat this as a supplement to a complete diet rather than the whole of it, and be aware that variety packs sometimes arrive weighted toward one flavour.
4. Earth Rated Dog Poop Bags, 270 Count — most reviewed here
$14.99 — 4.8★ / 249,041 ratings — #5 best seller
249,041 ratings at 4.8 stars — the most-reviewed and best-evidenced product on this page by a wide margin, and about six cents a bag. Earth Rated’s bags are noticeably thicker than the cheap generics, which is the one specification that matters here.
These are refill rolls, so you need a dispenser or a pocket — they do not come with one. Worth being precise about the environmental claim: these are described as leak-proof and lavender-scented, not compostable. If home-compostable bags matter to you, that is a different product line, and genuinely compostable bags cost more and tear more easily.
5. INABA Churu Lickable Cat Treats — cheapest here at $12.79
$12.79 — 4.8★ / 13,046 ratings — #6 best seller
Cheapest pick here and the treat that changed how people medicate and bond with difficult cats. It is a squeezable tube of creamy purée, fed by hand — most cats treat it as the single best thing that has ever happened to them.
The practical value goes beyond treats: it is the standard trick for getting a cat to take crushed medication, for coaxing a nervous cat out from under the bed, and for making vet visits and nail trims survivable. High moisture content too, which is a small bonus for a species that does not drink enough. Fewest ratings in this roundup at 13,046, though 4.8 stars across that is convincing.
6. Blue Buffalo Life Protection Chicken Dry Dog Food, 5 lb — $14.97
$14.97 — 4.7★ / 29,509 ratings — #13 best seller
The mainstream premium dry food that sells in volume without a prescription or a subscription. Real chicken first, no poultry by-product meal, and the little dark “LifeSource Bits” that Blue Buffalo is known for.
Two things to be clear about. This is the 5 lb bag, which is a trial or small-dog size — if you have a labrador, buy the 30 lb bag or you will reorder weekly at a worse price per pound. And if you switch your dog onto this, do it over a week by mixing increasing proportions into the old food; the digestive upset in the negative reviews is almost always an abrupt switch rather than the food itself.
7. Milk-Bone Original Medium Dog Biscuits, 10 lb — $14.97
$14.97 — 4.8★ / 81,743 ratings — #19 best seller
Ten pounds of biscuits — roughly 280 treats — for under fifteen dollars, which works out around five cents a treat. 4.8 stars from 81,743 ratings for a product that has been essentially unchanged for decades.
The hard-baked texture does help scrape teeth a little, though it is not a substitute for dental care. The thing to watch is calories: treats should stay under about 10% of a dog’s daily intake, and a 10 lb box makes it very easy to lose track. Break biscuits in half for small dogs.
8. Nutramax Cosequin Joint Supplement for Dogs, 132 ct — $34.91
$34.91 — 4.7★ / 79,563 ratings — #24 best seller
The joint supplement most commonly recommended by vets, at 4.7 stars from 79,563 ratings. Glucosamine and chondroitin in a chewable tablet, aimed at older dogs and large breeds prone to hip and joint trouble.
Set expectations honestly: joint supplements are not painkillers and the clinical evidence for glucosamine is mixed rather than conclusive. Owners who see a difference usually report it after four to six weeks of daily dosing, not days. If your dog is limping or clearly in pain, that is a vet visit, not a supplement purchase — arthritis has treatments that work considerably better than this, and limping can mean an injury that needs diagnosing. As a long-term maintenance product for an ageing dog, it is a reasonable buy.
9. Greenies Teenie Dental Dog Treats, 130 Count — $36.97
$36.97 — 4.8★ / 75,396 ratings — #25 best seller
Most expensive pick here, and the dental chew with actual clinical backing — Greenies carry Veterinary Oral Health Council acceptance for reducing plaque and tartar, which very few dental treats do. 4.8 stars from 75,396 ratings.
Size matters more than usual with these. “Teenie” is for dogs of about 5 to 15 lb, and giving a small dog a chew sized for a large one is the main way these cause problems — they are meant to be chewed down, not swallowed in chunks. Match the size to your dog’s weight and supervise the first few. At 130 count this is about 28 cents a chew, and one a day is the intended use.
10. Rocco & Roxie Enzyme Stain & Odor Eliminator, 32 oz — $23.92
$23.92 — 4.4★ / 127,373 ratings — #28 best seller
127,373 ratings for the bottle every pet owner eventually buys. The distinction that matters: this is bio-enzymatic, meaning live enzymes digest the uric acid crystals in urine rather than masking the smell. Ordinary cleaners leave those crystals behind, which is why a spot you cleaned still smells to your dog — and why they go back to the same place.
4.4 stars, joint-lowest here, and the technique explains most of the complaints. Enzymes need time and moisture to work: saturate the spot properly, let it sit for at least 15 minutes, do not scrub it dry, and treat old set-in stains twice. People who spray and immediately blot get poor results. Do not combine it with other cleaners either — bleach and vinegar kill the enzymes.
How we picked these
We pulled Amazon’s Pet Supplies best sellers on August 17, 2026 — 30 products — and filtered to 4.4 stars or better with at least 5,000 ratings. That left 29, which tells you something about the category: pet consumables that sell in volume are almost uniformly well reviewed, because owners reorder what works and abandon what does not.
With the rating filter barely cutting anything, the real work was deduplication. The list is heavily repetitive: four of the 30 are clumping cat litters, three are Milk-Bone treats in different formats, and there are two poop bag brands, two Fancy Feast variety packs, two Greenies lines and two squeezable cat treats. We kept the strongest entry in each group and dropped the rest, then balanced dog and cat products rather than letting dog treats take seven of ten slots.
A note on the source: the URL for this category pointed at a browse node that Amazon has retired — it returns an empty page and its best-seller list resolves to “Best undefined”. We used the main Pet Supplies best-seller list instead, which is the same catalogue one level up.
Where a product has a real limitation we said so: the pee pads vary in size by pack, 40 lb litter is heavy and clay tracks, gravy formulas are lower protein than pâté, the poop bags are leak-proof but not compostable and need a dispenser, the dog food is a 5 lb trial size and needs a gradual switch, dental chews must match your dog’s weight, and the enzyme cleaner needs 15 minutes and no other chemicals to work.
One thing we will not do in a pet roundup is imply a supplement replaces veterinary care. The joint supplement is a maintenance product for an ageing dog; a limping dog needs a vet.
