Nylabone Extreme Dog Chews Bacon 5 Sizes The Nylabone Extreme range of bones and chew toys are just right for your dog if he loves to chew, and is very good at it! These chew toys have a delicious flavour throughout, meaning the flavour goes on for as long as the chew does, they are not sprayed, dipped or coated in any way so there is no chance of that tasty flavour being licked off! The materials are as tough as real bones but they don't have the same dangers. We have been mastering making chew toys for over 50 years and have a manufacturing process like no other, we make sure they do not splinter, instead the nice smooth surface 'roughs up' as it is chewed and tiny bristles raise on the bone, acting like a mini toothbrush which will help keep your dogs' teeth clean and prevent tartar build up. If your dog does manage to bite any off it should only ever be as small as a grain of rice and these can be passed if swallowed, they are not a choking hazard.
