My 4-month puppy has diarrhea & no shots. Is it too late for vaccines?

No, it’s not too late and you should start those vaccines ASAP. Parvovirus is highly contagious and is devastating. The vaccine is highly effective but must follow a strict protocol. The veterinarian may also be able to give you an idea how old Marshall is. I hope this is helpful and please feel free to post any additional questions.

I'm sorry that Jorkey is having diarrhea. It is unlikely that the diarrhea is related to getting the vaccines. It is possible it is due to intestinal parasites or even the de-worming medication, if he received that on Saturday. Stress can also cause diarrhea, so if he was anxious or stressed about the visit, that could have contributed. I would recommend you take him back to your vet to have his diarrhea evaluated. He may need a temporary diet change, probiotics, and potentially an anti-inflammatory medication for his colon. He also may need to be checked for intestinal parasites and be de-wormed with a different medication. I hope he is feeling better very soon!

It could be a reaction. A dog can have vaccine reactions at any point in life. Reactions usually occur within 24-48 hours after vaccination. For the diarrhea, withhold food for 12-24 hours then feed a bland diet (plain, boiled boneless chicken and plain white rice) in small, frequent amounts until the stool is normal. Transition slowly to the regular diet. If t doesn't resolve, see your veterinarian. In the future, separate the vaccines to determine which vaccine caused the reaction. Your veterinarian can pretreat with an antihistamine to avoid reactions. Call your veterinarian and report the possible reaction.

Hello, this is a great question for your puppy. It is not too late for parasite control. Given his age and history of no dewormer it is recommended to take a fresh stool sample to your veterinarian. They will evaluate for what specific types of internal parasites he may have and get him started at least on a general dewormer. The dosing schedule and frequency of the dewormer will be deterimined by your veterinarian and the results of the fecal analysis. Thank you.

It very well could be parvo. I suggest you get her to your vet ASAP for an exam and testing. You really need to know if it is parvo or not. Either way, your vet will help you determine the cause of the bloody diarrhea and give you treatment options. Then, once this diarrhea is cleared up you can get her started on her vaccines. Hope this helps. Best wishes.

Depending on his age and vaccination history, he made need to restart the 5in1 series again and have 2 doses 3-4 weeks apart. The best thing would be to have a vet examine him and evaluate his vaccine history and determine which vaccines he needs and when.

Puppies commonly get gastrointestinal infections from parasites and bacteria that can cause this to happen. We always worry about Parvo virus in puppies, but it causes bloody stool, so hopefully this won't be the case for Stella. If he is still active and eating/drinking, then this is likely not an emergency, but he should be seen by a vet within the next 24 hours. They will be able to better determine the cause of this and prescribe the necessary treatment. I hope that helps and Stella gets better soon.
