Help My Dog Luca

On Friday afternoon, our house caught fire while we were away. Our dog Luca was stuck inside for 20 to 25 minutes with toxic smoke and has severe smoke inhalation damage. I have taken him to the vet twice now, paying outrageous bills that we as a family could hardly afford. When he is there, he is put on oxygen and is seen to be eating and increasing in health slowly. I have taken him home twice to see him struggle in breathing on his own and even eating. I am at a loss but I need to do everything I can to make sure my dog will be alright. I have to take him into the vet again and I’m asking for just some help from the general community. Anything helps. Thank you so much. Luca Brasi is our everything
