"My Lab/Beagle is an extremely strong chewer (he chewed through a Kong!) and this is the ONLY chew toy he hasn't gone through in a couple hours/days! Reilly has had his Galileo for over 6 months now and has barely chewed one knuckle off...It is his favorite bone! He takes it everywhere...outside, camping, bed, etc. Best investment I've made on a bone or toy!!!"
