If I have an emotional support animal do I legally have to tell the landlord before we get approved?

I have noticed we get denied after we tell them we have an emotional support German Shepherd. She’s an amazing dog and everyone just assumes she’s going to ruin there house. I have had a woman tell me no just flat out no when I told her I have a Esa .(which is illegal ??) I want that house very bad and I’m upset. I told her I could send her the papers and everything . It’s for my postpartum anxiety and she helps me so much. And she still said nope I don’t want animals in my house. Idk what to do. I’m thinking about having my husband call and fill out applications and not say anything to her and then afterwards tell her okay we have this esa. What do u think

We can’t find any places to move , we’re on a time limit and everything is so expensive right now. Idk what else I could do
