This is a specific conversation about Kong and chew toys — for serious chewers — ask about yours and get one honest answer for your exact situation.

A Caucasian Shepherd is one of the few breeds where you genuinely need to think hard about toy durability — those jaws generate extraordinary force, and an undersized or underbuilt toy won't last the afternoon. The right chew toy needs to be tough enough to survive serious pressure but not so rock-hard it risks cracking teeth over time. That balance matters. Tell me a bit more: is your dog a relentless, powerful chewer who destroys most things quickly, or more of a methodical gnawer? And what's prompted the search — boredom, destructive behaviour, something else?
He's 4 years old, male, absolutely massive — probably around 65kg. He destroys everything. We've gone through three rope toys and two rubber toys in the last month. He gets bored and chews the furniture when we're out.

Right, so you've got a classic combination — a giant breed with serious jaw strength, boredom as the trigger, and destructive chewing filling the gap. Rope toys and standard rubber were never going to hold up with a dog like that. The furniture chewing when you're out tells me he needs both a physical outlet and something mentally engaging. Before I point you to the right product — is he chewing solo when left alone, or does he also do it when you're home but not engaging with him?
Mainly when we're out, but sometimes in the evenings too if he hasn't had enough exercise. He's had a good walk today but he's still eyeing up the sofa leg.

That tells me the chewing is partly habit and partly an outlet for residual energy and mental restlessness — a stuffable toy will serve you much better than a plain chew, because the puzzle element keeps him occupied longer than just gnawing something hard. For a 65kg male Caucasian Shepherd, my clear recommendation is the Kong Extreme in XL. It's made from Kong's toughest black rubber, specifically designed for power chewers, and the XL size is built for giant breeds. Stuffed with something like peanut butter or Kong's own filling paste and then frozen, it can keep a dog like yours busy for a solid 30–40 minutes and gives him a reason to settle rather than wander. It won't be indestructible — nothing truly is with a dog his size — but it's the most durable stuffable option on the market and far more engaging than a solid chew. A plain solid rubber toy would last longer but wouldn't address the boredom side of things, which is clearly driving a lot of this.
Does freezing it actually make a difference? And how often would I need to replace it?

Freezing makes a significant difference — it slows him down considerably because he has to work harder to get to the filling, which stretches a 10-minute chewing session into 30 or 40. It also soothes any jaw tension, which big working breeds often carry. On replacement: with a dog his size and strength, inspect the Kong after every session. You're looking for deep gouges, chunks missing, or any sign the rubber is splitting. For most aggressive chewers in the giant breed category, the XL Extreme lasts anywhere from a few weeks to a few months depending on how often it's used and whether he's chewing the toy itself or mainly working at the stuffing. If you see him starting to tear pieces off the rubber rather than licking at the filling, retire it. Buy two so you can always have one frozen and ready — it makes the whole system much easier to sustain.
That's really helpful. I'll get a couple and try the freezing method.

Good call. Start with peanut butter or plain cream cheese, freeze them overnight, and give him one when you leave the house. You should notice a clear improvement in the furniture situation within the first week if boredom is the main driver. If after a month you're finding he's still restless beyond what the Kong covers, it might be worth looking at puzzle feeders alongside it — but start here. The Kong Extreme XL is the right foundation.
