We do the extra large size Kong. Stuff it with her kibble some water and a tiny bit of peanut butter, mix it around then freeze it for a couple hours. Keeps her busy. Also 'beef pizzle' bully sticks, but ones made in North America only. They don't last a ton of time but don't smell at all in our experience.What kind of chews is everyone giving to their large breeds? My Dobi chews through pretty much anything within 15 minutes. A lot of the stuff isn't safe.....alot of it is super expensive.....a lot really smells when they start chewing lol. Is there a new go to?
