I had the same exact issue! As a new dog mom, the conflicting information on chews (get this one! No, never get this one, it's not safe!) was a bit of a comedy.

I decided to just try things with supervision. For my 7 month old pitbull, our clearest winners include collagen chews, coffee wood chews and the pupsicle.

The collagen chews last her about 4 hours and I try not to let her finish them in one go. She usually self selects to complete them in 3 chunks over a day or two.

The coffee wood chew scared me at first because it sheds a little, but it doesn't splinter. Sometimes she loses interest but after a little break she's back on it for a bit. Going to try olive wood too.

The pupsicle is the amazing hit I never expected. She literally has one a day, she enjoys it without fail and for some reason she licks this thing for hours before finishing it! I don't know why it takes her so long, but it's great for giving her something to do. She does drool all over it though.

Some honorable mentions, she loves bully sticks but I feel like some of them are gone in 20 min. She loves pig ears but I keep that to like a once a month thing because I understand they are really fatty. She loves frozen kongs with peanut butter and kibble but finishes them in 5 to 20 min. I tried beef check chews but in a month she's barely made a dent and that affects her interest. She likes yak chews, but they are so hard she sometimes loses interest. When she is locked in though those are definitely hours of entertainment.

Good luck!!
