Okay, so I bought these for Labrador, Female, 4 years old, active, with a ferocious appetite. Thus far, these are The Only chews that
1. She is interested in. If the chew isn't food, she doesn't want it.
2. Lasts long enough to be worth our while - most chews, from the triple braided bullysticks to the absolutely massive bull pizzles that are like 60 bucks and thicker than two thumbs, last her for sub-10 minutes. A frozen, locked XL toppl lasts her just over half an hour.
These things? These wonderful, wonderful rock hard chews of apparently deliciousness last her, on average, an hour an a half. Some, she gets tired chewing on and SHE ACTIVELY WALKS AWAY FROM, like, insane.
Anyway, I'm buying like another 10 because goddamn, these things are fucking GOLD, you hear me? Gold!!!!
