#1 Best Overall: Seresto Flea and Tick 8-Month Prevention (Cat and Dog Versions Available)

With spring here and summer rapidly approaching, pet owners need to keep the fleas under control. Unfortunately, it seems like fleas and ticks become resistant to the prevention treatments faster than we can apply them to our pets! So, having a few options available to try helps keep these biting disease carriers at bay. 

Seresto uses two medications in its collar to kill and repel the bitey little pests: imidacloprid and flumethrin. But, instead of a greasy spot-on treatment or a medication your pets have to eat, Seresto’s active ingredients gradually spread across their skin. So, when fleas or ticks make contact, it kills them.

While Seresto collars may not work for every animal, they’re a great option in the battle for your fur babies’ health and comfort. The affordable price point and up to eight months of relief make the Seresto Flea and Tick Eight Month Prevention Collar our favorite product this May at Costco. 

We’re including links to all three versions so you can get straight to the product you need. You can find the medicine for large dogs here, and the medicine for small dogs here. A link to the medicine for cats is below.

2. Best Furniture-Style Dog Crate: Living Essentials 65” Cooper Dog Crate Credenza

We’re all about making your home as comfortable and stylish as possible. But let’s face it: dog crates are usually ugly wire setups that function well but don’t look all that great.

The Living Essentials 65” Dog Crate Credenza solves that problem with a functional dog crate and a wonderful tabletop that works as part of your household décor. The right section has several storage shelves, and the left side is a 43” dog crate with two front doors — and a removable divider to give your pup even more space.

With a strong metal structure underneath the pretty outer shell, this furniture-style dog crate should last for several years. However, it’s important to note that most furniture-style crates are designed for dogs you’ve already crate-trained. It may not hold up to a large breed puppy trying to chew its way out.

Although most people were happy with their purchase, the construction in this one seems to be a bit inconsistent — a few customers mentioned that it was missing hardware or had a broken shelf.

Overall, we love the Living Essentials 65” Cooper Dog Crate Credenza, and for pure style and multi-function convenience, it’s our favorite this May at Costco.

  • The crate is available in two colors: white and brown.

3. Best Dog Bed: La-Z-Boy Addison Pet Sofa

We think the dogs may have better beds than the humans who serve them! 

This bed from La-Z-Boy puts your pooch in the lap of luxury. It’s made with human-grade materials and includes a cozy throw blanket for your dog to snuggle with on their new bed. The Addison Pet Sofa’s cushion also has a removable and washable cover. 

Pet parents love this for smaller dogs of up to about 50 pounds. Our only complaint is that it isn’t big enough for larger breeds. It looks like a smaller version of some human-sized La-Z-Boy furniture, so you don’t have to sacrifice style for your dog’s comfort. 

The La-Z-Boy Addison Pet Sofa gets our vote for the best dog bed at Costco this month — its quality and attractive design make it a fantastic choice.

4. Best Pet Waste Cleanup: Lucky Dog Poop Bags 40 Roll Pack with Dispenser

It was a beautiful day for a walk with your dog — until he decided to use the neighbor’s lawn for a toilet. And you forgot a poop bag. 

It’s happened to all of us, but as responsible dog parents, we try to pick up after our pooches whenever possible. So, make it easier on yourself with Lucky Dog Poop Bags. Costco carries a 40-pack of rolls, each with 15 bags for a total of 600 bags — including a carrying pouch. 

They’re biodegradable and made with cornstarch; these bags are strong and easy to open. The included canvas dispenser makes it easy to make sure you can always clean up after your dogs. Additionally, the leather loop on the dispenser will hold the used bags until you can get to a trash can.

Environmentally friendly and reasonably priced, the Lucky Dog Poop Bag 40-Pack is our favorite pet cleanup product this month at Costco.

5. Best Cat Tree: Catry Bradbury 7-Level Cat Tree with Hammock & Condo

Finding great cat trees isn’t always easy. It seems like they’re either really expensive or flimsy! This seven-level cat tree from Catry is a great solution. Although it’s not inexpensive, it’s more reasonable than many options.

At seven feet tall, it has plenty of vertical space your kitties can climb and explore. It’s best for smaller cats, so your Maine Coone probably won’t fit. A couple of people mentioned that the top cave is smaller than they expected, so bear that in mind. 

The hammock at the bottom is cradled between the support legs, which are wrapped in sisal rope. The design is well-thought out and the soft carpet that covers most of the other components is great for cats to play on and scratch. If you have particularly rambunctious cats, you may want to weight the bottom for some extra stability. However, this is a terrific, affordable choice for cats who love climbing, making The Catry Bradbury Seven Level Cat Tree our pick for the best cat tree for this month at Costco.

How to Save Money with Costco

Costco is known for offering amazing deals to members. 

Unfortunately, they don’t accept manufacturer’s coupons. However, Costco works directly with manufacturers to offer the best prices on bulk purchases to its members.

Coscto.com’s prices are sometimes different than in-store — be sure to check. Many items are also available online for nonmembers. So, while Costco reserves the best deals for its members, nonmembers can purchase some items through Costco.com. 

Regardless, your best bet for saving money with Costco is by purchasing a membership and by signing up to receive their email specials.

The Gold Star membership is $60 and the Executive membership offers more benefits and will cost $120 per year.
