Grandfathered pets

[Jennifer Atkins]

When I moved into my apt. in 4/14 I had two dogs and the complex had a two pet policy at the time. I signed a new lease in 3/15 and there were no issues about me having dogs still. One of my dogs passed away in 5/15 and I decided the end of 7/15 that I wanted to get another dog because I was feeling depressed and so was my other dog. I just received a letter from my landlord stating that they were just informed that I have another dog-a puppy and that my two dogs I had when I moved in were "grandfathered in" so they didn't have a problem when they went to a no pet policy effective 1/15. How can the specific dogs be grandfathered in but not any other dog I get that falls into the original pet policy? They state that they DO have a problem with me getting another dog and not notifying management and I have 8 days to removed the new dog or face eviction. I don't see why me replacing a dog that passed away makes any issues. I clean up after my dogs in the common areas and my apt is clean and the dogs are well behaved. There are tenants that have moved in after 1/15 that have pets so I am not understanding where all this is coming from. I pay my rent every month, sometimes two months at a time. They have empty apt and several other tenants that don't pay their rent and are like a revolving door here. I would think they would want to keep a tenant that pays her rent and does not cause any issues. What are my options here? I am not in a position to move and refuse to give up the newest addition to my family as she has been good for myself and my other dog. Thanks for any advice.
