It certainly sounds as though Toby is quite sick. One of the more common causes of acute vomiting, inappetence and lethargy in puppies is a foreign body that is causing an intestinal obstruction/blockage. Other possible causes of Toby's signs include a gastrointestinal virus (including parvovirus if he is not vaccinated) and parasites. Toby needs to be examined by his vet today and assessed for dehydration. Small, young puppies are particularly susceptible to dehydration and the onset of hypoglycemia (low blood sugar). Your vet will be able to perform a parvovirus test (if indicated) and abdominal x-rays to try to rule out a foreign body obstruction because this would require emergency surgery.

    It sounds as Xena is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. 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.

    I am sorry to hear about Gizmo. I would recommend getting him to a vet's office as soon as possible. If he is very lethargic, he should go tonight to an emergency vet. In young puppies they can become dehydrated and weak very quickly with these symptoms. We worry in young puppies with vomiting and weakness about parvo virus which can become life threatening if untreated. We can also have vomiting as a result of severe GI parasites, ingestion of foreign objects such as toys, and more. The vet can examine your puppy and may test for parvo virus and intestinal parasites. They can give injections that will help stop vomiting and fluids to help with dehydration. Best of luck to you and your puppy.

    I would recommend that you take Grayson to the vet. Puppies can get dehydrated pretty quickly. Common causes of vomiting include intestinal parasites, food intolerance or allergy, eating something they shouldn't have, intestinal blockage, bacterial or viral infection (including parvo virus), among a few others. After examination, the vet may recommend testing such as a parvo test or x-rays to determine the cause. At the very least, Grayson could get an anti-nausea shot and then you wait and see what happens over the next 24 hours. If the nausea, vomiting, or decreased appetite come back, then there may be something going on that needs more diagnostics to be run.
