Chew toys for Leonberger puppies

An 11-week-old Leonberger is already a serious proposition — these pups arrive big and only get bigger fast, which means standard puppy chew toys are basically useless from the start. Teething is one of the most intense periods of puppyhood, and having the right chew available — firm enough to satisfy that powerful jaw, safe for teeth that are still coming through, and ideally something you can chill to soothe sore gums — genuinely changes how much of your home survives. How much does your pup weigh right now, and is the main concern keeping them occupied and off the furniture, or are specific things already getting targeted?

9kg at 11 weeks is completely normal for a Leonberger — he'll likely be 60–70kg by the time he's done, so yes, you need to be thinking giant-breed from day one. 'Relentless' is the right word for this stage; their gums genuinely ache and they're not going to stop until something satisfies the urge. Chair legs and shoes are getting targeted because they're the right shape and firmness — so you need to give him something better to lock onto. Can I ask: does he tend to chew in long sessions, or is it more frantic short bursts?

That's really useful — it means he needs something with genuine resistance, not something that'll be shredded in five minutes. A lot of puppy toys are rated up by size but fail quickly with a breed that has this much jaw engagement. Given his age, his size, and those long focused sessions, I'd go with the Kong Extreme in size XL. It's made from ultra-durable black rubber — their toughest compound — so it holds up to serious, sustained chewing. It's also hollow, which means you can stuff it with soft food or frozen broth to extend those sessions and redirect his attention completely away from the furniture. Crucially, the rubber is firm enough to satisfy but not so hard it risks damaging his baby teeth, which matters a lot at 11 weeks. The XL size is appropriate for where he is now and will still be relevant as he grows through the rest of teething. Pop it in the freezer for an hour before you give it to him — the cold helps a lot with gum soreness at this stage.

Stick with XL for now. The XXL is sized for adult giant breeds and at 11 weeks he needs something he can actually get his mouth around comfortably — too large and he won't engage with it properly, which defeats the point. The XL will serve him well through the active teething phase, which runs until around 6 months. By the time his adult teeth are fully in and he's putting on serious mass, you can move up. For now, XL stuffed and frozen is exactly what you need.

At 11 weeks, keep it simple and gentle on his stomach. Plain low-fat cream cheese works well and freezes nicely, as does a little peanut butter — just make sure it's xylitol-free, that's the thing to check on the label. Puppy-safe wet food is another good option, or you can just plug the small end with a dog treat and pour in some diluted low-salt chicken broth and freeze the whole thing. The frozen broth version is honestly the best for teething specifically because the cold does real work on sore gums. Start with one stuffed Kong a day when he's most likely to go looking for trouble — that post-walk wind-down window is often prime chewing time.
