Pet Supplies You Should Buy At Costco To Save Money

Paying for your pet's supplies, along with everything else these days, has become more expensive than ever. In fact, according to the American Pet Products Association (APPA), U.S. consumers are projected to spend $157 billion on pet supplies and services in 2025 alone. Of that total, $67.8 billion is just on pet food and treats, while another $34.3 billion is due to be spent on supplies and over-the-counter medicine.

According to APPA's 2025 State of the Industry Report, a whopping 94 million U.S. households own a pet — with the most popular being dogs at 68 million households. Furthermore, a 2023 survey from Total.vet found that the price of dog food (both dry and wet products) had increased by an average of 45.5% when compared to 2020 prices. This leaves a significant portion of the country spending more on the absolute basic necessities required to care for their pets. The survey also found that 50% of respondents reported having to shop for cheaper pet food alternatives as a direct result of these rising costs. This applied not just to food, but also treats, toys, and supplements.

This is where Costco can come in, and, in many ways, be a lifesaver for pet owners. While there are absolutely mistakes to avoid when shopping at Costco, buying your pet supplies and food is not one of them. In fact, when comparing Costco prices across a myriad of pet supplies and food, it is the clear winner when stacked up to pet supply stores like Petco.

For starters, buying pet food at Costco can come with some serious savings. According to a 2023 comparison from The Motley Fool, via barchart, both dried dog and cat food cost over $1 less per pound when compared to Petco offerings. Similarly, flea and tick treatment prevention products cost significantly less at Costco. An 8-pack of FRONTLINE Plus flea and tick treatment for large dogs (45 to 88 lbs.) is listed for $96.99 on Petco's website, as of July 2025. However, Costco lists the same product for $79.99 on its website. With that said, that Costco price includes shipping and handling, meaning that chances are good a consumer can score this item for even less when shopping in-store at their local Costco location.

When it comes to supplements, Costco's prices are similarly more competitive. For example, A 4-pack of 55-count Cosequin Feline Sprinkle Capsules, a common supplement to help pets with their joint health, is listed on Costco's website for $43.99. Meanwhile, at Petco, a single 60-count package of Cosequin capsules retails for $17.49. Running the numbers, Petco's option costs roughly 29 cents per capsule. This means that in order to reach the same 220-count of the Costco option, you'd spend over $64 at Petco. Perhaps the most important thing for a pet owner to realize when it comes to taking advantage of Costco pricing on pet supplies is that you will have to bulk buy to truly get the best bang for your buck. While most Costco shoppers are probably already familiar with this concept, those living in smaller homes might have to consider where they'll store 24 cans of wet dog food.

Costco pet lovers should know that the savings don't stop at food and supplies. Another less-well-known Costco offering that can save you money is the warehouse chain's in-store pharmacies. Costco happily fills pet prescriptions, and even boasts of savings of up to 40% compared to other pharmacy offerings. Plus, Costco offers a wide selection of potential pet medications, from heartworm treatment to allergy medications to antibiotics, ensuring they will have whatever your pet might need. Another perk is that most Costco locations will provide home delivery for your prescriptions, saving you an extra trip. The best part is that there is no additional sign-up required to use the Costco pharmacy for your pets – simply being a part of the Costco Member Prescription Program is all that is required.

Another potential product that pet owners might want to consider through Costco is pet insurance. While there are certainly pros and cons to pet insurance – especially when you consider just how many companies are dropping policies — depending on your pet's particular needs you might be curious about the possibility of a plan for your pet. Costco partners with Figo pet insurance to offer discounts on insurance premiums for Costco members. Gold Star and Business members can save 15% while Executive members can save 15% and receive Figo's 24PetWatch lost pet recovery service. Figo's policies cover things like chronic conditions, imaging, and hereditary conditions. Also, keep in mind that Figo can also help to reduce your pet's prescription costs even further, meaning a policy could be worth more research.
