Scale of "sure" to "hell no" should I let our tenant get a puppy?

[John Knowlton]

Hi everyone,

I have a tenant (three young men/roommates) renting a nice single family home of ours.  They have have been in the house about a year and have been good tenants so far (except they often wait until the last minute to pay rent).  We are generally a pet friendly landlord and initially allowed them to have a cat for $35 month.  One of the guys reached out to see if we would allow him to get a golden retriever puppy.  The house has a fenced in yard, wood floors and vinyl plank on the main floor but new carpets upstairs.  I want to be accommodating to keep our tenants happy but I am concerned about the puppy aspect. What do you all think or what would you require?  Does anyone have a good pet policy I can use?

Thanks for your help and advice!

John
