What Every Dog Owner Should Know About Internal Parasites
July 19th, 2010Dogs can become infected with worms in many different ways, luckily most of these worms are species specific and are transferred from dog to dog, but some worms and parasites can be transferred among different species. This should not be a concern if you routinely worm your dog to reduce the risk of your dog, other pets in the household and your family from becoming infected with parasites and worms.
The most common source of parasitical contamination occurs between dogs. A dog can easily pick up parasites when playing with other dogs that are infected with worms or from sharing food and water dishes. Dogs can also become infected by worm infested fecal material as the parasites will burrow into your dog’s paws. Any time your dog is in an area where there are many dogs, he is at risk of contracting internal parasites.
The most common types of worms that infect dogs are: roundworms, tapeworms, hookworms and whipworms. Tapeworms and roundworms can easily be detected in the feces or around the dog’s anus, hookworms and whipworms are too small to be seen with the naked eye but can be detected by the vet with a stool sample examination.
Roundworms: Roundworms resemble earthworms in appearance and can reach up to five inches in length.
Many dogs are born with roundworms and as it is dangerous to worm a young puppy special care should be taken to ensure the mother is worm free during pregnancy to avoid contamination of the puppies. Roundworms can infect the mother’s milk and become passed on to the puppies when they nurse.
The worms survive in the intestines and each worm can lay up to 200 eggs a day. Some of the eggs are eliminated in the feces while the majority of the eggs remain in the digestive tract. When the eggs hatch they move around the dog’s body and enter the lungs causing irritation and coughing. When the dog coughs, some larvae are discharged into the mouth and become swallowed and enter the digestive system once again and the cycle continues. The number of worms increases dramatically and a severe infestation can lead to a pot bellied appearance and a severe cough and death may occur if the intestines become blocked by the ever-increasing number of worms.
Hookworms and Whipworms: Hookworms are the more dangerous of the two as they can cause severe anemia and death in dogs by feeding on the dog’s blood. Whipworms can cause dogs to become lethargic and whipworm infestations are common in kennels and boarding facilities.
Tapeworms: Tapeworms are passed to pets from fleas and they can infect cats and dogs. They can be detected as small white particles resembling rice grains on the anus and hair of dogs. Dogs that like to hunt small animals and rodents are particularly at risk of tapeworm infection. These worms are persistent and you should consult with your vet if you notice small, flattened white segments on your dog’s anal region.
Routine worming is vital if you want to keep your dog healthy. Over the counter worm treatments are not very effective so you should get your vet’s advice who can devise a regular worming schedule to help keep your dog safe and healthy.
