There are so many horror stories about many items but I'd rather give my GSD pups something safe..er to chew on that them to start teething on my furniture or trying to find relief with sticks or door posts
( yes, one did ).
It's choosing the safest option for the breed of dog. That said, sticks, stones and balls ( unless attached to a rope ) can be very dangerous as I know of many dogs that have lost their lives over the years. However in 25 years I've only seen one dog have a problem with a raw hide chew and it was a very small, narrow one still hard as unchewed.The large ones need some chewing to get bits off which softens them enough to help them through the digestive system. I love using the huge ones for pups.
The nylabone I wouldn't use again after I treated my terrier and GSD to one each of appropriate sizes. They are not edible yet both dogs chewed them up. Luckily it passed through them with no side effects.
Kongs are great, can be stuffed with breakfast or treats, frozen meat in for teething and great interaction with owner. Black ones are very tough red ones fine for gentler mouthed dogs.
Tried a stag bar after recommendation. Removed it after a few hours when it started splintering. Just like bone, it is indigestible and small pieces can build up compacting andcausing blockage or severe constipation. Or the risk of splinters piercing the stomach or intestines and causing peritonitis.
I personally think the choice is in the type and nature of the individual dog. The health risks being taken into priority.
I use ball on a rope for training but would never leave my dog with one as he would chew the rope which is dangerous in itself and then the risk of the ball getting stuck.
