Good luck, you are so kind. That was a dreadful night. The dogs home were really good with us, we attempted to rescue a staffie from them, but the poor girl despite only being a baby just needed different to what we could offer. They took her back and placed her in dog therapy with just a couple as foster parents. So even if this one doesn't work out, they will help you with no judgement.
Ohh, good luck! Those poor babies, I guess a lot of them will have issues relating to the fire. If not physical, then mental/ behavioral due to the trauma. As if it wasn't difficult enough to find homes for rescues
