I have 2 very strong 100 lb chewers! Knuckle bones last about 2 weeks, forget anything rawhide.. even deer antlers last a matter of hours. So far, these have lasted several weeks with only the tips chewed off! Yes, they are more interested in the knuckle bones with gristle, but these smell better and are a nice diversion!
