One of the females seems to be sick today--she didn't want to eat and I gave her NutriCal. I've been giving them antibiotics. I'm worried about her and the others but I don't know what else to do.
I went back in the afternoon and the puppy looked a little better--she even ate a little. I will still give antibiotics to all of them, just in case and will check on them tomorrow.
There's another new small puppy at the beach--more or less the same age as the 6 pack. I don't have pictures yet, but tomorrow.
