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 7-month-old Bullmastiff is in a prime chewing window — the jaw strength is already serious, the habits aren't yet fixed, and this is exactly the right moment to get the right outlet in place. The right chew toy needs to be durable enough to survive a breed built like a small car, but not so hard it risks cracking those developing adult teeth. A lot depends on how your dog actually chews — methodical and grinding, or explosive and destroy-everything? Tell me: is your pup a moderate chewer or already levelling furniture, what's prompting the search right now — boredom, destructive chewing, something specific they've gone after — and have you tried any chew toys with them before?
He's definitely destructive — got through a rope toy in about ten minutes yesterday. He's been going for chair legs and shoes. Nothing specific has happened, I just want to get ahead of it while he's still young. Haven't tried much yet, just that rope toy and a basic rubber ball.

Ten minutes on a rope toy from a Bullmastiff puppy is pretty standard — those are not the right tool for this dog. The chair legs and shoes tell me he's not being naughty, he just has a strong chewing drive and nothing appropriate to direct it at. The good news is you're catching this early, which makes a real difference. Before I tell you what I'd go with, one quick question: does he tend to carry things around and gnaw gradually, or does he attack something in one focused session and then lose interest?
He'll go at something really hard for like 20 minutes, then wander off. So focused bursts rather than all-day chewing.

That's actually helpful — focused burst chewers do really well with food-stuffed toys because the engagement is mental as well as physical, and it gives those sessions a natural end point. My clear recommendation for you is the Kong Extreme, size XL. It's made from Kong's toughest black rubber, specifically designed for powerful chewers — it's a completely different material to their standard red range. You stuff it with something like peanut butter or wet food and freeze it, which extends that 20-minute session and makes him work for the reward. It satisfies the chewing drive, keeps him off the furniture, and because he has to problem-solve to get the food out, it tires him mentally too. For a 7-month-old Bullmastiff building good habits, this is exactly the right foundation. I'd get two so you always have a frozen one ready.
Does freezing it actually make a difference, or is that just something people say?
inparticular.ai
It genuinely makes a difference. Unfrozen, a dog like yours will empty a stuffed Kong in a few minutes. Frozen, the same Kong can hold his attention for 20 to 30 minutes because he has to lick and work at it rather than just shake it out. It also means you can prep a batch on a Sunday and pull one out whenever you need it — which is much easier than stuffing one from scratch each time. The cold is also soothing on gums in a dog still coming through with adult teeth, which at 7 months he likely still is.
That makes sense. Is the XL definitely the right size — I don't want to get one that's too small.
inparticular.ai
XL is right for a Bullmastiff at 7 months and will see him through to adulthood — Bullmastiffs typically finish around 50 to 60kg, and XL is rated for large to giant breeds. Too small and there's a swallowing risk; too large and it's awkward to carry and engage with. XL hits the mark. If anything, err toward XL over L — you won't regret having slightly more room to stuff it.
