Yes, I would have said that because usually you have far less chance of a nylabone breaking.
So sorry about your friend's dog - I can fully understand your worries
Adult nylabones are stronger than the puppy ones but there are other options.
I use raw beef marrowbones from my butcher, and also pigs ears, occasionally. Steer clear of any kind of cooked bone. Kong do bone shaped toys which may be more flexible than nylabones and so less likely to break.
There's also a range of very strong dog toys which I'll hunt down and get you a link to. They survive well even in my house
So - no cooked bones? I didn't know that, will avoid.
The link looks good - they are expensive but OTOH we have spent more than that on toys which have been destroyed quite quickly (she's gone through 5 or 6 at about a fiver each), so one that actually lasts would be worth it.
I was when she pooed out a label one day - I picked up the poo and it said "keep away from fire" on it - took a few seconds to realise it must have come off a cuddly toy
