Wild Wolf 9-12" Peanut Butter Beef Collagen Cheek Rolls for Dogs (4 Pack) - 100% Natural Big Dog Chew - No Rawhide - Free-Range Grass-Fed, Packed with Protein - for Aggressive Chewers

Okay, these are a little bit pricey, but they last. It takes about 5 days for my 100 LBS super chewer to eat one. So the entire pack lasts around 3 to 4 weeks. Regular bones will take him about 30 minutes or less to chew up and be ready for the next thing to chew. https://www.amazon.com/dp/B0GYG3VSXN?ref=ppx_yo2ov_dt_b_fed_asin_title
