What to Do If Your Puppy Has Parvo and Worms

If your puppy is vomiting up worms, they need to be treated. Worms are going to make your puppy sicker, and the parvo infection will be a lot worse. Roundworms cause diarrhea and vomiting, which further aggravates parvo infection. But in order to treat the worms, the puppy has to stop vomiting.

There are a lot of good deworming products on the market that work well on puppies, including a very safe product called pyrantel pamoate that you can buy at pet shops and stores like Walmart. Do not give the medication until the puppy is no longer vomiting.

For the Best Chance of Survival, Go to the Vet

To have the best chances of surviving both parvo and worms, a puppy needs to be hospitalized and be given intravenous fluids and medication to stop the vomiting. They must also be fed a special diet or be kept on glucose until able to eat. (1)

At-Home Parvo Treatment

If you cannot afford to have your puppy hospitalized, you can try to treat the pet at home, but there is a much greater possibility that they will die. You can ask the vet to let you take home fluids to give the puppy subcutaneously, pick up a prescription of metoclopramide to decrease vomiting, and then take your puppy home.

As soon as you get there, make up a special bland diet for the pet and offer it about every hour. The sooner the puppy starts eating, the better their chances. (2)

Bland Food for Puppies

To make up the bland diet, use:

  • 1 chicken breast
  • 1 cup of boiled white rice
  • 3 tablespoons cottage cheese

I mix all the ingredients in a blender and serve it warm. The food does not look appetizing, but the warm smell may encourage your sick dog to eat.

How Long Does It Take Puppies to Recover From Parvo?

Taking care of a puppy with parvo is a lot of work, but it does not take a lot of time. The amount of time your puppy will need to recover varies depending on how bad things are, but usually in about a week, a puppy will have recovered from the virus.
