The only time they enter my home is if they are given as a gift.
I don't see the point in giving them - my three would much rather chew on a real bone, it's much tastier to them and has a greater nutritional value. Besides, rawhide tends to give dogs build-up/tarter on their teeth. I used to give them often until I realize how nasty their teeth were getting.
They now get free-range cow bones and their teeth are so much whiter because of it!
