Whipworms

What are whipworms?

Whipworms are intestinal parasites that are about 1/4 inch (6 mm) long. They live in the cecum and colon (large intestine) of dogs where they cause severe irritation to the lining of those organs. Whipworm infection results in watery, bloody diarrhea, weight loss, and general debilitation.

 

They are one of the most pathogenic worms found in dogs.

How do dogs get whipworms?

Whipworms pass microscopic eggs in the stool. The eggs are very resistant to drying and heat, so they can remain viable (alive) in the  environment for up to 5 years. Once laid, they embryonate (mature to an infective stage) in the environment and are able to re-infect the dog in 10-60 days. The   embryonated eggs are swallowed and hatch and mature to adults in the lower intestinal tract, completing their life cycle (see illustration).

How are whipworms  diagnosed?

“Parasites pass small numbers of eggs on an irregular basis, so some samples may be falsely negative.”

Whipworms are diagnosed by finding eggs with a microscopic examination of the stool. However, multiple stool samples are often required because these parasites pass small numbers of eggs on an irregular basis, so some samples may be falsely negative. In addition, it takes approximately 11-12 weeks after hatching for a female adult to begin to lay eggs.  Any dog with chronic large bowel diarrhea should be suspected to have whipworms, even if the stool sample was negative.
Thus, it is an accepted practice to treat chronic diarrhea by administering a whipworm dewormer. Response to treatment is an indication that whipworms were present but could not be detected on fecal examination.

How are whipworms treated?

There are several drugs that are very effective against whipworms. At least two treatments are needed, spaced at a three to four week interval. The most frustrating aspect of whipworm infections is the high rate of re-infection because the eggs are extremely hardy in the environment.  Therefore, if a dog is diagnosed with a whipworm infection, it is advisable to treat again every three to four months. The other option, which is much simpler, is to use a heartworm preventative that contains a whipworm medication. Whipworms are not nearly as common today because of widespread use of these modern heartworm prevention products.

Can I get whipworms from my dog?

No. Whipworms are not infectious to people. They are exclusive parasites of the dog.

Puppy Care

Congratulations! Bringing home a new puppy is fun, but it is also a huge responsibility that lasts its lifetime, which can sometimes reach 12 to 18 years or longer. The first six months of your puppies life are the most critical and establishes his health and behavior for the rest of his life.puppy You, as the puppies advocate, must ensure he is protected from disease with a series of vaccinations and effective monthly parasite control. Thousands of inadequately vaccinated puppies never make it to see their first birthday because of diseases such as parvovirus and distemper. Thousands more will die from heartworm disease from the bite of one single mosquito, and even more may succumb to intestinal parasites, such as hookworms, even before they even reach 2 months old.

The majority of dogs relinquished to animal shelters is usually because of behavioral issues, such as dog aggressiveness that results in a dog bite, the inability to house train or unruly and destructive behavior. These are natural tendencies in dogs, and it is your responsibility to learn the how the dog thinks and use the natural, instinctive pack leadership skills to effectively modify both you and your dog’s behavior and solidify a great and rewarding relationship with your new puppy and family

Puppy proofing your home is another safety precaution you must establish. There are several hazards to young puppies you must look out for, such as electrical cords, toxic houseplants, foods that must not be fed, and toxic substances that need to be secured. Providing a safe haven for your puppy, such as a crate, when you are away, will keep him out of trouble and will also hasten house training.

There is so much more that I want to share with you that I have developed a series of newsletters and videos to help you take great care of your puppy and then well into his senior years. Register for my puppy care newsletter and you will also get some bonus e-books.
