"No pet policy " but i seen 2dog

I found this nice apartment. When i 1st went to go look at them there was a dog right in front of the office, and i was like yes they allow pets. No one was there to talk to so i left. I went by there today and saw 2more small dog, with there owner right outside of the office. This time i talk to someone and i ask how much was there pet fee and can u believe they say no pet. WTH!! im like but yet their are 2 dog outside this office just chilling. i really want this apartment and i was thinking about being my dog anyways. Is it a bad idea or no?
