Update & to Thank everyone for all their great advice. Hopefully, also to help others with their babies same symptoms.
Vet visit today. Seems to be a Virus. Bella was given a shot for nausea & pills for diarrhea.
Cole seems to be getting better today. YAY!

His same symptoms have lasted about a week now.
Hopefully, Bella is on her way as well.
I also had Bella checked for Coccidia. We found out that our other grandoggie Noah...well, he was being treated for it & he had visited. Very strange in an older dog, but she rescued him & has no idea of his earlier shots. I wanted to cover all bases. It did not show up for Bella. So seems to be a Virus. Cole had it first....then less than a week later, Bella got it.
Hope everyones babies stay Healthy! Thanks again for YT & the great members!!!
