I do not feed my two raw hide bones.. but when i do buy them treats, i am always looking for a good chewing time/ money ratio. My mom gives her husky and doodle bully sticks and they last them for ever!! She told me about them.. I went and bought some... $6 each!! Ouch... and Taurus' was gone in 30 mins... Jada's ( she was only about 9 months at the time) one hour!! Not enough bang for my buck there!!
They currently have bones that were bought at Super Pet by my mom for her dogs. Her two couldn't even pick these bones up they were so big, so she gave them to us. They have had these bones for 6 months!! Im not exagerating either... They each chew on them for about an hour a day, and they're still working on them. They are hollow inside, but they have a smoky smell... so I think the inside tastes smoked...
I also give them soup bones, I go to the butcher and buy a bag ( 4-5) for $2 .... so that is defenitly worth it. The onlt problem is that it gives them the runs... so they dont get them very often!!
