pets and amending our document

Earlier this year we had a members meeting to vote on amending our documents to allow pets. It failed to pass getting only 33% of the vote.

But the more I thought about it, I don't think we needed a vote to amend our documents. It appears to me that our document (Master Deed) gives authority to the Board regarding pets. Our document reads as follows:

"The keeping of any pet on the Property shall be restricted according to provisions of the Associations's Rules and Regulations as amended by the Board from tiem ti time, provided however. that in no case may any type of fish, fowl, or animal be bred, or kept or maintained for commercial purposes on the Property."

The lawyer that is also a Board member told us we needed 100% yea vote to amend the document to allow animals.
I don't intend to open this can of worms again, but I was wondering what your take on this is. Someone in the future could bring it up again. (Our document does require 100% vote to amnend anything in Article 6 and this is where the pets are mentioned.

With very little to go on, it's possible that the Board may amend the number and type of pets if pets are allowed. However, if pets are prohibited, then you must follow the specified method to amend the document.

Of course, without reading the actual document, this is just a wild guess.
