Payments for pet deposit

I got woody few months ago. He became a huge part of our lives. I have three children who loves woody alot. If I don't make this payment I would have to get rid of him. It's killing me and I don't wanna have to see my kids be upset that their dog has to go. I was working two jobs and pet deposit was only 200 but now landlord raised to $250. I got fired and relying on 711 which isn't much especially with rent coming up. I can't take woody back to the pound cause they will mark him as not adoptable and probably put him down . anything helps! Thank you in advance.
