Rottweiler teething to adult chews at 21 weeks

Teething is one of the most intense periods of puppyhood, and at 21 weeks your Rottweiler is almost through the worst of it — but that doesn't mean the chewing stops, it just changes character. Having the right chew toys available, ones that are firm enough to satisfy but safe for developing teeth and ideally chillable to soothe sore gums, makes a genuine difference to how much destruction happens. So — 21 weeks, nearly through teething: is the main concern managing the last bit of teething discomfort, or are you already thinking about what kind of chew enrichment will keep a young Rottweiler satisfied long-term as those adult teeth come in properly?

That makes complete sense — Rottweilers don't really have a gentle phase when it comes to chewing. At 21 weeks he's got most of his adult teeth coming through and the drive to chew hard is only going to intensify as his jaw strength builds over the next few months. Can I ask, is he chewing more out of boredom and energy, or is it more frantic and urgent like he's still getting relief from gum discomfort? And is he currently destroying everything he gets hold of, or do some toys actually hold his interest for a decent stretch?

The evening frantic chewing is really common at this age — they're tired but overstimulated, and the jaw just needs something to do. Freezing a rubber toy is exactly the right instinct, and the fact that it's helping confirms he's still getting some gum relief. The issue is most standard rubber toys aren't built for a Rottweiler jaw that's becoming genuinely powerful. My recommendation is the Kong Extreme, specifically the large or XL size. It's made from Kong's toughest black rubber — it's genuinely a different material from their standard red range — and it's designed for powerful, persistent chewers. It's hollow so you can pack it with something like peanut butter or wet food and freeze it, which gives you the soothing cold plus a long engagement session that tires him out mentally. It'll comfortably handle a Rottweiler into full adulthood, so you won't be replacing it in three months. It's widely available on Amazon UK and reasonably priced given how long it lasts.

At 21 weeks a Rottweiler is already a sizeable dog and will grow quickly, so I'd go straight to the XL. With the large there's a chance he grows out of it within a couple of months and smaller Kongs carry a slight risk of getting lodged if a powerful dog really goes at it. The XL gives you room to pack in a decent amount of filling too, which extends how long it keeps him busy. Fill it, freeze it overnight, and hand it to him in the evenings — you should notice a real difference in that frantic chewing window.

For a 21-week puppy, plain peanut butter — make sure it's xylitol-free — is the easiest starting point and most dogs go absolutely mad for it. You can also mix in some of his regular kibble with a bit of wet food to create a paste, freeze it solid, and it becomes a real project for him. As he gets older and more experienced with it you can layer different fillings and freeze in stages to make it harder to extract. But honestly, frozen peanut butter in a Kong XL on a Tuesday evening will already feel like a revelation.
