Our dog is a chewer! Fabric toys don’t last - he enjoys ripped them apart. This lasts quite a while. I do watch it because after sometime (month or so), he does get it start separating. He actually got it in half once (looked “interesting” on my floor when we found it and made for a good laugh). We will continue to buy them.

GOOD CHOICE FOR A SUPER CHEWER

Size: Large (Pack of 1), Size: Large (Pack of 1)

Pretty good choice, but for a super power chewer like my 2 year old ROTT, nothing can stand up to her ! This bone usually lasts her about 2-3 weeks, but we only let her have it a few hours a day to keep her busy.
