Intestinal Worms: The Basics
Parasites are like pirates . . . they will commandeer your pet like pirates take over a ship. You cannot always see parasites but that doesn’t mean they do not exist!
Parasites have evolved to leech nutrition from their host while simultaneously trying to evade detection and death by the host. Intestinal worms are a common health concern for many species, canines included. The most common intestinal worms in dogs are: hookworms, roundworms, whipworms, and tapeworms.
Symptoms of intestinal worms:
- Diarrhea, sometimes bloody
- pot-bellied appearance
- Generalized unthriftiness
- Ravenous appetite
- Occasional vomiting
- Scooting rear on the ground
Severe infestations can lead to anemia, intestinal blockages, emaciation and death.
Your dog can acquire worms throughout a lifetime in a few common ways. With treatment like Drontal Allwormer that exists, hopefully, your dog doesn’t have to suffer from this for too long. Young puppies with worms are either born already infested with worms or get them shortly after birth. Larval worms can pass through the uterus to the fetuses during gestation, or through the mother’s milk to the nursing puppies. Adolescent or adult dogs acquire worms by ingesting eggs in fecal-contaminated environments, by eating infected rodents, or by ingesting fleas that contain the eggs. Speaking of fleas, for any pet to have to suffer from this can be very uncomfortable. They become such a nuisance for both the animal and the owner. For some people, it can get to the point where the assistance of a pest control colorado company, for example, might be their last resort. This way, you are able to take control and get your home looking and feeling as good as new.
The worm eggs will hatch inside the dog, then migrate throughout the dog’s body and develop through stages, eventually developing into adults. Dogs with adult intestinal worms will shed eggs to the environment through the feces.
Adult worms live in the intestinal tract of dogs and hijack nutrients from their host. Some species of adult worms can grow very large and can occasionally be seen in the feces. Worm eggs cannot be seen with the naked eye. A microscopic exam of the feces performed by a veterinarian can help diagnose intestinal parasites, even if your dog does not display other symptoms of worms. This should be done yearly as a part of your dog’s routine checkup. Even dogs on monthly heartworm preventatives can still acquire worms and may need additional medication to treat an infestation.
There are a variety of deworming medications available. The type of medication used is based on the type of worms being treated. No one medication works for all worm types. Prescription medication from your vet are usually more effective than over-the-counter medications and can be prescribed best based on the fecal exam results.
I highly recommend monthly heartworm prevention for all at risk dogs. Heartworm medication prevents against heartworm infestation (a different type of parasitic worm), as well as regularly rids dogs of the common intestinal worms. Even after treatment, dogs can easily be reinfested through the routes listed previously. If your dog is not on heartworm prevention, they should still be regularly dewormed every few months for preventative care.
Do not begin any new medications or heartworm preventatives in your dog without first discussing it with your regular veterinarian.
Some intestinal worms of dogs can infect humans! Discuss this topic further with both your regular veterinarian and physician.
