Hi Tracey,
Sorry to hear the bone didn't last, I do appreciate the feedback. A photo for me to access would be appreciated as well.
I was surprised to read you hadn't given your dog the Harold toy. The Harold toy is my overall strongest toy and has the most reviews on my website to back it. I'm sure it has a much better chance of lasting with your staffy!
I understand it's because of the squeaker, It does have an internal squeaker that cannot be removed however you can break it. Simply jam a pen into the hole at the end of the toy, try and push it the whole way in and that will break the squeaker!
I hope this helps and you do give your staffy the toy, I'd love to hear how it goes!
