My 9-week-old puppy is coughing and throwing up. Is it heartworms?

Updated On September 23rd, 2025

Pet's info: Dog | Siberian Husky | Female | unspayed | 2 years and 5 months old | 52 lbs

So I have a puppy that is 9 weeks old and has been on dewormer since they were 2 weeks old every 2 weeks like directed, but as of 2 days ago one of the puppies has begun coughing and then today has thrown up twice. I'm really worried that it's heart worms but don't really have the money to take him to the vet as of this moment... I was wondering what your opinion is and is there any possibility it's something less, you know, life threatening...

If you are concerned about the puppy at 9 week old having heart worm disease this is not possible. Heart worm disease takes 6 months to develop from immature to adult worm. That means a 9 week old puppy is not able to have heart worm disease. However bacterial, viral and even parasites like roundworms can cause coughing. I would recommend taking the puppies to a vet for a good check up that way you can determine why they are coughing. hope that helps
