Why is my 3-month-old Labrador puppy having diarrhea and vomiting?

Shino could have parvo, a severe stomach illness, or a foreign body causing the vomiting and diarrhea. She is really sick, and this cannot be treated at home. You need to take her into a vet immediately.

Buck could have a parasite or infection causing the vomiting and diarrhea. Your vet can test a stool sample and prescribe medications to treat. He may need a dewormer, antibiotic, anti-vomiting, and/or other medications to help treat. You can also feed a bland diet of boiled chicken and white rice and add a probiotic to see if that helps.

I'm sorry, it looks like your original question about Luna got cut off, as all we were able to see is "Our 5 month old female lab was vomiting." If her current issue is frequent urination and accidents in the house, she may have developed a urinary tract infection, which is unlikely to be related to the vomiting (if the vomiting has since resolved). I recommend that you take her to your vet, as a urine test can be performed. If it is discovered that she does indeed have an infection, antibiotics will be needed to clear it up.

Start Diamond on just boiled chicken and rice (with no oil or seasonings) for the next 3 days. If the stool doesn’t firm up within a day or so, your friend’s vet can run a fecal exam for intestinal parasites and prescribe metronidazole (flagyl), an anti-inflammatory antibiotic for the gut that shortens the duration of diarrhea as well as a probiotic such as VetriScience Fast Balance. Good luck!

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!

4 days is very long for a dog to have vomiting and diarrhea. I recommend that Alexa see a vet as soon as possible. Potential causes for her illness include dietary intolerance, dietary indiscretion, food allergy, intestinal parasites, GI blockage, gastroenteritis, bacterial or viral infection, IBD, pancreatitis, among others. Your vet may recommend abdominal x-rays, bloodwork, or an intestinal parasite screen to help diagnose her ailment and create an appropriate treatment plan.

Poor pup! He should see a vet right away, as it's recommended to see one when a dog is both vomiting and having diarrhea. He could have a severe GI illness, may have eaten something rotten, have pancreatitis, or a foreign body. I would take him into a vet now, who can diagnose what is causing his symptoms and treat accordingly.
