Rawhide chews - yay or nay ?

Our (old- as I have since moved) butcher used to make his own rawhide twists- i doubt they were bleached- they were a dark brownish colour and very crunchy/chewy- he used the skins from the products he sold - Tassy loved them shame we moved. She never had a blockage or poorly tummy either.
 
Sorry to hijack post but - What do people fill their kongs with? i'm not buying that squirty stuff it costs a fortune and looks revolting. At the moment i stuff one with chicken roll which is cheap but not sure how healthy it is! My ridgeback loves it, she was not keen on peanut butter! Interested to know what others use but as much as i love her i refuse to buy chicken breasts or anything else that costs a fortune!

I have a kong for my springer, she gets fed up with trying to get the stuff out and leaves it. I used to put laughing cow triange cheese in it, or peanut butter, I used to stuff it with small biscuits first then put the cheese or peanut butter just round the inside to stop them coming out, she'd either pay with it until it all came out then leave it. I tried those things you can slot in but she got fed up of those too and just used to leave it because it was too hard to get out.
