How can I find an apartment with a big dog?

Hello, I’ve had my dog (great dane/ pix mix) for a bout two years. I adopted him while living in an apartment and didn’t tell management about him. I was living with an ex and he had a dog that we got approved and paid fees for.

I unfortunately had to move back home and I can’t find any places that would take his breed. I don’t even get a chance to plead my case because of the pix mix aspect. He’s a good quiet dog and doesn’t have issues with other dogs or people. I don’t make a ton of money, but I’d pay any fees. I just don’t know what I should be looking for specifically with most of the apartments having breed restrictions.

I’m scared id have to give my dog up, this is my baby. If anyone has advice I would be so grateful, thank you in advance 😭
