I'm no authority on this. But I've seen similar situations, and when it came to taxes, it did not turn out good for the individual who was in the same position you are in right now.
I would expect your dog club to be registered as a non-profit organization, which means the organization would have their own Federal Employer Identification Number (FEIN) and a bank account set up using the organization's FEIN. I would also think the club would have their own facebook page. If that's not what you have, then all that needs to be set up yesterday, if not sooner. Otherwise, if the organization is not set up as a non-profit and registered as a charitable organization, then someone is paying taxes on that money like it or not. Presently, that person is assumed to be you. Now I don't know this for a fact, but I would expect that if an SSN or EIN is not provided in a timely manner, then FB may very well shut down the fund raiser.
