In either case, I would give them BOTH notice that you are ending their tenancy but offering a new one upon them completing an application (so you know who is there) and signing a new written lease (even if month to month, that way you can have such things as no pets no smoking etc) even if you offer them rent at the same rate.

Asked questions like do you smoke, do you have pets, eviction/criminal record, number of people moving in, gross monthly income, etc. 

Just food for thought. 

Or for the future you could add a clause to your lease in the pet section that addresses excess barking and fines them additional fees if the city issues a citation, or however you want to word it that works for you.Good luck

They will have access to the whole house, but will bring their own food and such. 

You can set up your chart of accounts to track the different income for the rental (ie Rent, application fee, late fee, pet fee, etc.), expenses like tax, insurance, interest, repairs, turnover expenses, and also the usual admin & overhead expenses.

Address their issues as a responsible landlord and charge them for their pets if you charge a pet fee in all of your rentals.

Pet deposits are typically not refundable.
