What is whipworm in dogs?
Whipworm (scientific name Trichuris vulpis) is an intestinal parasite that can seriously impact your dog's overall health. Measuring about 1/4 of an inch long, these parasites make their home in your dog's large intestine and cecum where they attach to the mucosal lining causing extensive irritation. What causes whipworm in dogs is a dog swallowing infective whipworm eggs in soil or other substances that may contain dog feces.
What do whipworms look like?
This intestinal parasite can be easily identified by its shape. They have a thicker front end and a long thin back end that look much like a whip.
What is the whipworm lifecycle in dogs?
The whipworm lifecycle consists of three stages: egg, larvae, and adult. The eggs are laid in the dog's intestine and become part of the dog's stool. This means that a whipworm-infected dog spreads whipworm eggs with each bowel movement. The eggs are extremely hardy and can survive in the environment for up to 5 years.
Once out in the world, the eggs typically mature into the infective stage in about 10-60 days, at which point they are ready to infect the next host animal. Soon after they are ingested they hatch and mature in the pet's intestine where they lay more eggs and begin the cycle once again.
What are the symptoms of whipworm in dogs?
If your dog was recently infected, there will likely be few signs of a whipworm infection, and some dogs will remain asymptomatic even in later stages of infection (show not symptoms). However, some of the most common whipworm symptoms in dogs are as follows:
- Chronic diarrhea
- Weight loss
- Blood in stool
- Anemia
How is whipworm in dogs diagnosed?
Fecal exams at your vet's office are the best way to monitor your dog for intestinal parasites including whipworm. Whipworm takes up to 12 weeks to mature and begin laying eggs, and tend to lay limited numbers of eggs and on an inconsistent basis. For these reasons, diagnosis can be tricky and may require repeated fecal exams to reach an accurate diagnosis.
What is the treatment for my dog's whipworm infestation?
Because whipworm eggs are so resilient, reinfection often occurs making whipworms a challenging parasite to get rid of.
Whipworm treatment for dogs includes prescription medications to kill the parasites living in your dog's intestine, as well as additional medications to treat any uncomfortable symptoms your dog may be experiencing. Most whipworm medications in dogs require two treatments spaced about 3-4 weeks apart. It will be necessary to thoroughly clean your dog's bedding, kennel area, and dog run to help prevent reinfection. Your veterinarian may also advise you to re-treat your dog every 3-4 months to help fight reinfections.
Can I prevent my dog from getting whipworm?
Yes! In most cases, prevention is far easier and more effective than treatment. Many heartworm medications for dogs also provide whipworm protection. By giving your pet monthly heartworm medication, you may also be protecting them from a variety of intestinal parasites such as whipworm, hookworm, and roundworm. Inquire with your veterinarian about the best ways to protect your dog.
