The listing shows they will accept cats. That being said, quite often, if your application and credit report etc look excellent to the landlord, exceptions may be made. However, you indicate that you have a puppy so it may depend on the dog breed and how big they would be at full growth and the current age. Also, there may be restrictions in this building that they only allow cats overall.
You would be best served working with a realtor who can assist you with all this and if you do not already have an agent and would like help, one of our agents would be happy to do so. Please feel free to give us a call.
