Can condo association force out owners of oversized pet dog?

I signed a year lease to rent a condo that stated I have 2 dogs and paid a $200 pet deposit, now the Property Manager for the condo association is saying we are in violation of rules and regulations. We were never provided a copy of these rules and can not find on internet. Other tenants have big dogs as well and the limit is supposedly 25 lbs.  If our lease states we can have dogs and were never provided rules and regulations, can the condo association force us out of a year lease?
