i have been living in my apartment for over 7 months. before i moved in i told my landlord that i have a small dog. my landlord notified the HOA manager for permission if i can move in with the dog and he said to give it a try. the HOA has a no pet policy except for one grandfathered dog. i know that there are other pets in the building. recently the HOA made me remove my pet. is it leagal for the HOA to have me remove my dog and allow the other pets to reside?
