Puppies sick in hurricane - home remedies?

We rescued a litter of 5 puppies (approx. 2–3 months old) off the street. Owner of mother dog didn’t want them so let them roam, but they almost got hit by a car.

Besides intestinal worms and fleas, they seemed perfectly healthy.

Today we bathed them in Dawn for fleas and put them back in the yard. A few hours later when we went to get them to put them in the kennel, they were making a rasping, coughing sound. They continually made it when they got excited, except for one, who seemed to do it almost constantly.

Just now when I let them out to potty, they seemed a little disoriented. It’s hard to tell because it’s dark, but it seemed that some of their steps were off.

I live in Louisiana, and the hurricane is supposed to hit in a few hours. The vets offices will be closed until Friday at least, and my internet will be down in the next 24 hours.

Is there anything I can do for these puppies until the vets office reopens? They haven’t come in contact with any other dogs or puppies since we got them, approx. 5 days ago… I’m not sure what it is they have, but it came on very suddenly at the very worst time.
