Animal bones in toothpaste

I am a student of B.Sc. nutrition.  In syllabus I studied that bones of dog r mixed in Colgate.  I want to ask that is it right to use that ?

If in reality, some bones or some other body part of a dog or some other forbidden animal are being mixed in that toothpaste, then use of that toothpaste is not allowed and is forbidden.

Still, the experts should investigate this well.  Without any research, the proper Shariah ruling cannot be given.

And Allah knows best.
