Hello and welcome!
I have never had to do that either...but I do know that it is a common procedure.
As Linda said, most vet offices and groomers will do this for you. (Thank goodness!)
But I have seen instructions on how to do it...I can't recall where, but probably in books or online. If I come across any again I'll send you the info.
My last dog Ollie, a lab/shepherd mix, was a chronic scooter and the techs at his vet's office would take care of it for him. (on their lunch hour...could you imagine? ech!) It is not a job for the squeamish (me) and I really hope Sawyer does not have this issue!
