I'm afraid that if you value your job with this Vet...
the Vet's position has been very clearly stated to you -
YOUR personal opinions, thoughts, and advice to Customers is NOT to be voiced.

You may want to attempt having another *private* conversation with the BOSS Vet;
but you've already tried that once...
"I went on and did my commercial for Soft Paws, but I really didn't have an audience. "

MY "read on this" is that the Vet's mind was made up a Long Time Ago - and will take an even longer time to change. Being a new employee, you sort of agreed to "follow the office rules" when you came on board. Seems an important "rule" will be voilated if you offer your Don't Declaw message to any customers.

One of the quickest ways to get into trouble with the BOSS will be when
a Customer tells the Vet "Your receptionist said ..."

Sadly, I think you're between a Rock and a Hard Spot. Good Luck with
whatever you decide to do.

EDIT:
Just read your last post ~
Good Plan; but a word of caution!

Be very careful that you don't jump on your Soap Box *in the office*...
I predict the BOSS Vet will have a Zero Tolerance for it.
