The Causes of Worms in Dogs

There are a variety of worms that cause illness in your dogs such as: heartworms, hookworms, roundworms, tapeworms, and whipworms. What causes worms in dogs? Let’s take a closer look.


Hookworms are predominately found in dog feces. If your dog eats these feces they can develop this condition. Look for the following signs: loose stool or blood in the stool, the dog seems bloated, gas, has an unusual appetite, and his coat seems to be on the dull side.


Roundworms come from dogs ingesting the egg of the roundworm. In puppies, they may become infected through the mother. Signs that your dog has roundworm may be exhibited as follows: vomiting, diarrhea, bloating, gas, and an unusual appetite.


Heartworms are usually developed from mosquitoes. This condition can result during warm months when dogs are more exposed to these pests. Signs your dog may have heartworm includes: lethargy, coughing, appetite loss, difficult breathing, and may become more tired than usual after exercise. This condition requires immediate treatment from a vet.


Tapeworms are caused by dogs eating fleas. A regular inspection of your dog’s rectum to detect if there are any white rice-like parasites will clearly indicate your dog has tapeworms. Other signs may include: itching in the infected area, inability to digest food,
loss of weight, and stomach pain.


Whipworm is caused by dogs that eat other feces that have been infested with worms or if they happen to step in feces and lick their paw. A dog with this condition will have a bloody stool, unusual appetite, will become bloated, experience cramps, and have a dull coat.


There are other serious conditions which can affect a dog’s health, particularly puppies. While these are not attributed to worms, they should nonetheless be noted. Coccidia are parasites which are caused by digesting feces. Signs of this condition includes: loose stool, vomiting, loss of weight, and bloating. Coccidia infect the intestines of the pup.


Another parasite which can affect pups is called Giardia. Found mostly in areas where water is abundant, the ingestion of these parasites can cause loose stool, loss of weight, and bloating. These parasites feed on the small intestine.


Detection and early prevention can alleviate the symptoms affecting your dog or puppy.
A regular check-up will give a vet the opportunity to check for worms and other conditions by taking stool samples. If you find that your dog’s behavior or habits have changed in any way, make an appointment with your vet to ascertain the problem so that treatment can commence immediately.


Note: Some parasites can affect small children. To prevent this from occurring, ensure that your child does not come into contact with the dog’s feces. After your child plays with the dog, make sure he or she washes his hands thoroughly each and every time.


Giardia in London (UK) shelter : Worms and Germs Blog

A recent paper in the journal Veterinary Parasitology (Upjohn et al 2010) described a study looking at Giardia infections in dogs in a central London shelter. The researchers collected a fecal samples from dogs within 1 day of arrival and tested them for Giardia.



  • 21% of dogs were shedding Giardia on arrival at the shelter.


  • Shedding rates were higher in younger dogs.

  • Of the samples that were genotyped, almost all were Assemblages (types) C and D, the dog-specific types that are not thought to be able to cause disease in people.


This is one more study highlighting a couple of important facts about the protozoal parasite Giardia:




  • Giardia is common and can be found in healthy and diarrheic dogs. Studies of healthy pet populations typically reported lower rates than the 21% found here, but it is not uncommon to find Giardia in approximately 7% of healthy pet dogs.

  • Young dogs are more likely to be infected. That’s also true for various other intestinal microorganisms that can cause disease. 

  • The majority of dogs that are shedding Giardia are infected with types that do not infect people. This is an important point and it needs to be considered when people are worried about infections from dogs (or trying to blame pets for human infections). There is limited risk of transmission of Giardia from pets to people. That doesn’t, however, mean no risk. Since a small percentage of dogs can shed Giardia types that can infect people, common sense should be used when handling dog feces. Even if a zoonotic strain of Giardia is present in a dog’s stool, it has to make it to someone’s mouth to have a chance of causing an infection. Proper handling of feces and basic hygiene practices (especially hand hygiene) should greatly reduce the already low risks.

WORMS AND INTERNAL PARASITES OF DOGS AND CATS

Dogs and cats are susceptible to parasites. You can prevent and treat parasites very easily.


TYPES OF TEST


FECAL STOOL EXAM is used to diagnose the presence of intestinal parasites. A fresh stool sample from pups or kittens should be tested by your veterinarian when they are 6-8 weeks of age. Adult pets should have their stool tested every six months or at least yearly.
When you adopt a new dog or puppy, it is recommended to get a fecal test after about 10 days of the dog being home. Even if the dog or puppy had a fecal exam completed once brought into the rescue, the stress of going into a new home can weaken the immune system and resting parasites can surface. The average incubation period for parasites is 10 days.


HEARTWORM EXAM is used to search your pet’s blood for evidence of heartworm infection. Puppies should be tested at six months of age. Adults should be tested annually in the spring. If you are bringing a dog in from a shelter ask if a heartworm test was done. If not, get a heartworm test immediately.


TYPES OF INTERNAL PARASITES
ROUNDWORMS of ascarids are intestinal parasites found in both dogs and cats. But the common ascarid of cats does not infect dogs and vice versa. Roundworm infection can be fatal in young puppies and kittens. These large worms fill the small intestine and interfere with the absorption of nutrients. Signs of roundworm infection in dogs include a pot belly, diarrhea, dull scruffy coat and weakness


WHIPWORMS are bloodsucking parasites that live in the large intestine. They cause inflammation, bloody stool and diarrhea. Your pet will experience abdominal pain, general malaise and a decreased appetite.


HOOKWORMS are bloodsucking parasites found in both dogs and cats. But the common hookworm of dogs does not infect cats and vice versa. Hookworm infection can cause severe, even fatal blood-loss especially in pups.


TAPEWORMS are common intestinal parasites of dogs and cats. Fleas, rabbits, mice, rats and other animals carry and intermediate stage in the life cycle of tapeworms. Dogs and cats become infected with tapeworms by eating these carriers. The most common tapeworm of dogs and cats is carried by fleas. If your pet is exposed to fleas, watch for tapeworm segments passing with your pet’s stool.


COCCIDIA are intestinal parasites of dogs and cats which can cause diarrhea and weight loss. Coccidiosis usually affects young dogs and cats, especially those from places where large numbers of animals are kept together, such as kennels, catteries, pet stores and puppy mills.


GIARDIA is a single-celled parasite that lives in your dog’s intestine. It infects older dogs but more frequently infects puppies. Dogs become infected when they swallow Giardia that may be present in water or other substances that have been soiled with feces. Giardia infection, usually results in diarrhea. Having giardiasis a long time can cause weight loss; generally poor condition; and even death, when the disease is serious.


HEARTWORMS are most common in dogs, but cats have been known to be infected. They are parasites that spend their adult life in the heart and large blood vessels. They are transmitted by mosquitoes. Heartworm disease is a serious and potentially fatal disease in dogs. Much of the damage occurs before there are any outward signs. Therefore, prevention is the key in protecting your dog.


When your dog is diagnosed with an intestinal parasite, make sure you clean your hard of any fecal matter immediately after elimination to prevent reinfecting your dog or puppy. If your dog or puppy has accidents in the house, use bleach when possible to kill any remaining parasite.


Always consult your veterinarian with questions or concerns.
