Baily is so cute! I am concerned though that he is not eating and having such intestinal upset. I would recommend you take Baily in for an exam with your vet as soon as possible. Puppies this young can get dehydrated very quickly and become quite ill. I am worried about the possibility of intestinal parasites, eating something he shouldn't have (dietary indiscretion), or even a bacterial or viral infection (like parvovirus). Baily may need some tests to see what the underlying cause is, such as a parvo test and fecal test. He also may need some anti-nausea medication, antibiotics, or even fluid therapy if he is dehydrated. I hope he gets back on track quickly!

    It sounds as Jess is suffering from a gastrointestinal condition, possibly an infection. i would recommend taking her to the vet the first chance you get, she will need to be checked first, if the vet thinks it's a simple gastrointestinal infection she will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better. if the vet thinks it is more serious she will need a blood test and possibly an ultrasound in order to find out what is wrong.
