Starmark Everlasting Dog Treat (2 Treats)

The Verdict

If your dog demolishes a bully stick in under ten minutes, you’re probably tired of spending $12 a week on chews. The Starmark Everlasting Dog Treat doesn’t just give your dog something to chew — it gives them a puzzle that takes days to solve. At 4.5 stars from 225 ratings, it’s clearly working for a lot of frustrated pet parents. But it’s not a magic bullet, and here’s what you need to know before you buy.

What’s Actually in the Box

You get two Everlasting Treats and two refill inserts. The treat itself is a textured, non-edible plastic wheel with a grooved center that holds a compressed, edible insert. The design is clever: your dog has to work the insert out through the grooves, which slows them down dramatically compared to a standard chew. The plastic is made from a tough, food-grade polymer that’s designed to withstand serious jaw pressure. Each insert lasts a few days for moderate chewers, and the plastic wheel itself is meant to be reused indefinitely with refill packs.

Real-World Performance

The magic here is in the mechanics. The grooves are angled so that a dog’s tongue and teeth can grip the insert, but it doesn’t come out easily. Dogs that usually power through treats in minutes will spend 30-45 minutes on this, and the insert often survives multiple sessions. The treat is also designed to float in water, which makes it great for bath time or pool play — a feature that gets surprisingly little attention but is genuinely useful.

Build quality is solid. The plastic has some flex to it, so it absorbs impact rather than cracking under pressure. Owners of pit bulls, labs, and other power chewers report that this outlasts almost everything else on the market. One buyer noted, “My German Shepherd destroyed every toy we bought in under an hour. This one lasted three weeks before she finally cracked the plastic.”

What Buyers Love

The durability is the headline. Over and over, reviewers mention that this is the only chew their aggressive chewer hasn’t destroyed in a single sitting. The refillable design is also a big selling point — you can buy just the inserts (about $8-10 for a two-pack) instead of replacing the whole toy. Owners also appreciate that the treat is low-odor, unlike rawhide or bully sticks, which can stink up a living room.

Where It Falls Short

First, this is not an edible treat. Once the insert is gone, the plastic wheel is just a toy, and some dogs lose interest entirely. If your dog is motivated purely by food, you’ll need to keep refills on hand or the toy will end up in a corner.

Second, while the plastic is tough, it’s not indestructible. A determined chewer can eventually chip or crack it, and those sharp edges can be a safety concern. Supervise the first few uses, especially with power chewers.

Third, sizing is limited. The largest size works for medium dogs, but owners of giant breeds like mastiffs or Great Danes report that it’s a bit small for their jaws. Check dimensions carefully before ordering.

Who Should Buy This

• Owners of aggressive chewers who are tired of replacing destroyed toys weekly
• Dogs that get bored easily and need mental stimulation, not just something to gnaw
• Pet parents who want a low-mess, low-odor chew that doesn’t leave crumbs and stains everywhere
• Budget-conscious buyers who want a reusable base with affordable refills

Skip it if your dog is a light chewer who prefers soft, plush toys — they’ll likely ignore this entirely. Also skip it if you have a giant breed; the sizing just isn’t there.

FAQ

Is this safe for aggressive chewers? Generally yes, but supervise the first few uses. The plastic is tough but can eventually crack under extreme pressure. Replace it immediately if you see chips or sharp edges.

How long does one insert last? For moderate chewers, 2-4 days of occasional chewing. For intense chewers, expect 1-2 days. It varies a lot based on your dog’s chewing style.

Can I put other treats inside the plastic wheel? Yes, many owners stuff it with peanut butter, wet food, or freeze it for an extra challenge. Just be aware that wet fillings make a mess when the dog works them out.

The Verdict

Buy it if: You have a powerful chewer that destroys everything else, and you want a reusable, refillable solution that actually lasts.

Skip it if: Your dog needs an edible treat to stay engaged, or you have a giant breed that needs a substantially larger chew.

Rating: 4.6/5 — It’s not perfect, but for the right dog, it’s the best-value chew on the market. The durability and refillability make it worth the upfront cost, especially compared to the weekly replacement cycle of cheaper alternatives.
