Puppy fell, hit head, now throwing up, won't eat. Is it serious?

Vomiting after an head trauma might be concerning. I recommend to bring her to the vet for a physical and neurological examinations to exclude brain damages (i.e. concussion). Please post again on the forum if you would like to discuss it further. I hope my answer was helpful.

Julia should be examined by your veterinarian today. Vomiting and a lack of appetite in a puppy can quickly lead to dehydration which can kill. If she is not vaccinated, diseases such as distemper should be ruled out. At the very least, she may need supportive care (IV or subcutaneous fluids, anti emetics and parenteral nutrtion) until she is eating on her own and not vomting any longer.

Poor Molly! I'm sorry to hear that she's having this problem. Yes, if she has hit her head hard enough to cause these symptoms, I'm afraid that this is definitely an emergency - head trauma is a serious, life-threatening problem in dogs just as it is in people. Even if her symptoms are due to something else, they are still a sign that something is seriously wrong so I would really recommend having her seen regardless. It would be best to take her to your nearest emergency clinic right away for an exam - the vet there can do some diagnostic testing if needed to determine what's wrong and get her started on appropriate treatment.

Just like humans, pets can vomit for many many reasons. It can be something more minor like a bacterial infection or it could be something potentially fatal like parvovirus (if your puppy is not properly vaccinated) or an intestinal blockage. I recommend to play it safe and have Princeton examined by the veterinarian tonight. Puppies who don't eat may run the risk of having low blood sugar or dehydration. It's always best to play it safe. I hope it's nothing too serious and please feel free to post any additional questions.

I would be very concerned that Brooklyn is suffering from head trauma if she is sick to the stomach and has pain in her head. There is nothing you can do for her at home for this, head trauma can be very serious and requires veterinary treatments. She needs to see a vet now. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

Lola is extremely sick. I see that she is unspayed, and her symptoms could be caused by a pyometra. This is an infection of the uterus that is fatal without treatment. You have to take her into a vet immediately.

Yes, your friend can take Lola into the vet. If she's 13 days old, it's very serious that she isn't eating or drinking. Young puppies are very fragile, and whenever there is a problem with them (especially if they aren't eating), it's considered a medical emergency. Have your friend take her into a vet immediately.
