Not exactly raw, but what do you think of these cow's ears as a chew treat? I have a very chewy dog, and if I run out of rec bones to feed her I like to have some bullies or other chew alternatives around. TIA!
I've never tried those but my dogs like tracheas. They don' last terribly long, about like bully sticks. I got them from bestbullysticks.com
also split pigs feet (from the grocery) take mine a while to eat.
