Regular worming is essential to protect your dog against internal parasites. This involves giving it preparations in liquid or tablet form. Adult dogs should be wormed at least once a year, and at least once every six months if in contact with children. Dogs showing any signs of infection should be wormed immediately and all breeding bitches should be wormed prior to mating.

Roundworms.
Several of these parasites affect dogs but the most important are the ones that belong to the Ascarid family, and live in the small intestine. Other roundworms infest the large intestine, blood vessels and respiratory tract. Ascarids feed on digesting food in the dog’s gut, and are particularly harmful to puppies. They penetrate a puppies gut wall and pass via the blood to the liver and then to the lungs. From there they crawl up the trachea to be coughed up and swallowed, again ending up in the gut. Infected puppies may develop :-

Hepatitis, pneumonia, fits, and obstruction to the gut, so regular treatment is vital.

As the puppy gets older most of the worms travel to the muscles, where they form cysts. These lie dormant until the puppy bitch becomes pregnant. They then migrate to the puppies lungs, and this is why virtually every puppy is born with roundworm, and must be wormed regularly.

How do I know if my pet has worms?

Cats: A number of intestinal parasites will produce no visible symptoms in your cat at all – or at least not at first. Other parasites such as the tapeworm will usually be visible in your cat’s feces and in the hair or on the skin around his anus.

Other symptoms of worms in cats may include:

* Vomiting
* Persistent dry cough
* Swollen abdomen
* Anemia
* Diarrhea
* Persistent scratching around the anus
* Weight loss
* Eating a great deal without putting on weight
* Breathing problems
* Bad breath

Dogs: In many cases you may not even know that your dog has worms without having a sample of his feces analyzed. Certain intestinal parasites such as tapeworm however are usually clearly visible either clinging to the skin or hair around the dog’s anus or in a fresh feces.

Other symptoms of worms in dogs may include:

* Weight loss
* Gastrointestinal disturbances
* Diarrhea
* Anemia
* Scratching, particularly around the base of the tail
* Vomiting
* Mild to severe coughing
* Eating a great deal without putting on weight
* Bad breath

Feline parasites, such as roundworms infest cats in almost the same way as worms in dogs. This process is usually completed in three ways.

* The cat can consume worm eggs from the soil. These roundworm eggs generally come into the environment from the excretion of other infected dogs and cats. The eggs have the capacity to withstand environmental changes and are immune to mild disinfectants. The sticky egg shells cling to the paws or to the fur of the pet. Cats generally ingest the eggs by licking the places where these eggs cling to.
* Most kittens are infected through their mothers. Roundworms have a long migrating lifecycle inside the body of a cat. Larvae get encysted in tissues and can remain there for years. The litter of an infected mother is already infected in utero. Larvae can also be passed on to the kittens through milk during the lactation period.
* A cat can ingest an infected host animal like a rodent. Larvae in the host develop into roundworms within the cat’s body.

The first stage of the roundworm lifecycle is while it is dormant in the environment. This is the period before it actually infects the host. This fact means that fresh feces are not infectious.

Tapeworms are intestinal parasites that can infect cats and dogs alike. However the kind of tapeworms that cats are most susceptible to are different from those that infect dogs in most cases. Cats are most likely to be infected by three groups of tapeworm species.

* Dipylidium caninum
* Taenia
* Echinococcus

In most cases the manner in which each of these groups infects the cat is different. The Taenia species infects a cat when it eats a prey that is already infected. Dipylidium caninum infects cats when they eat lice or fleas that carry larvae of tapeworms. Echinococcus infection is through eating raw meat or carrion of an infected host.

Tapeworms comprise of segments. The segments towards the extreme that carry eggs are shed off and these reach the environment when the host excretes. Tapeworms require a minimum of two hosts to survive. The intermediary carries the larvae that live in the tissues of the host. The larvae develop into adults when the secondary host is eaten by a primary host like a cat or dog.

The dog tapeworm, Dipylidium caninum, is the second most common tapeworm after the Taenia species in cats. Its typical lifestyle comprises of the following stages:

Roundworms are common feline parasites that can infect cats of all ages. During a lifetime practically all cats get infected at one time or another because roundworms can even transmit to kittens through the lactating mother.

There are two species of roundworm that predominantly infect cats.

* Toxocara cati
* Toxascaris leonina

Eggs of Toxocara cati pass through the feces of an infected cat. The embryonic worm in the microscopic egg needs a month in the open environment to reach its infective stage. Having reached the infective stage, Toxocara eggs can weather harsh conditions and survive for years.

This second stage larvae are ingested by a cat or by another animal. They hatch in the intestines. This is the primary host of the roundworm. The young roundworm then migrates and gets encysted in other body tissues of the host.

If the primary host is a cat, larvae get encysted in the cat’s liver. From here onwards the larvae can take two routes depending upon the condition of the host cat.

Owning a pet has certain responsibilities. You have to feed and groom it as well as keep them away from various diseases. This is what cat care and health is all about and by doing it correctly, they can live for 10 years or even longer.

Cat vaccinations are the most effective means of fighting a disease. This also prevents the cat from ever becoming a carrier. Some of the common vaccinations given are for cat flu, feline leukemia or FeLV, Feline Chlamydophilosis and Feline Infectious Enteritis or FIE.

If your cat is given a vaccination, be aware that they may experience some side effects. This goes away shortly even if they develop flu like symptoms or fatigue in the next dew days. In rare cases, the cat may develop cancer where the injection has inserted that may develop in weeks, months or even years.

Cats just like humans experience allergies. This may come from pollen, dust, disinfectants and others. If you notice your cat experiencing any symptoms, you should stop using such products, keep them away from plants and make sure your house is clean.

Hookworms are considered to be the most pathogenic of all canine and feline parasites including roundworms and dog tapeworm.

Hookworms are excessively greedy blood suckers and cause extensive loss of blood. They ‘hook’ on to the walls of the intestines and draw out blood and ingest it directly. Some can bite and cause lacerations which result in blood leaking. To add to the miseries, the esophageal glands of the hookworm secrete an enzyme that inhibits blood coagulation.

Hookworms can penetrate skin and infect humans as well. Barefoot humans and children who play in areas where dogs defecate are at a high risk of infection. A study of the lifecycle of hookworms can go along way in achieving the goal of treating hookworm infection and eradication of hookworms from the environment.

Depending upon the species, an adult hookworm can lay up to thirty thousand eggs in a day. A moist loamy soil and warm temperatures are most conducive to hookworm survival. But these hardy parasites have been known to survive in tougher climatic conditions also. Unlike other worms in dogs hookworms develop in feces only when the feces are broken up naturally by earthworms or rain. Larvae in their infective stage move out from the feces and wait in the soil or vegetation for a host to pass by.

Roundworms have evolved in a manner that they can thrive in almost any environment. They can be found in freshwater, sea water and even in terrestrial environs. There are nearly 20,000 species of roundworms out which 15,000 are parasitic. They are also the most prevalent of the worms as compared to all other types of worms in dogs.

Many dogs are born with roundworms. These are generally passed to them by their mothers through the uterus or through the mammary glands. A mother can transmit larvae that are lying dormant in her tissues or organs to the fetus of her puppy. She can also transmit the larvae while nursing since the larvae can enter the mammary glands and pass on to the young one.

There are, however, other ways in which roundworms can enter the body of a dog. The most common among them is by ingestion. Dogs can consume roundworm egg or larvae infected feces since many dogs do have a tendency towards coprophagy (eating feces). They can also ingest larvae by eating other infected animals like rodents.

There were times when it was believed that the only way worms in dogs passed on to puppies, was through the mother’s system while they were still in the uterus. Whereas this contention still holds good for some types of worms, it has now been established that worms can infest puppies through other means also.

Worms like dog tapeworm, and dog roundworms and even some feline parasites have a typical lifecycle and can enter a pet’s body through various means.

Worms are intestinal parasites that reside mostly in the small intestines. Worms like tapeworms and roundworms are extremely migratory within a dog’s body and they are expelled and ingested during different stages of their lifecycle. Infestation can be through ingestion of larvae or eggs of worms or through ingestion of infected intermediate hosts like rodents and mice. Worms are passed through feces and puppies ingest worms directly from the environment as well. Sometimes the infection can be passed on by contact with the coat of the infected mother.

Parasites 5 Nasty Internal Parasites Your Dog May Have

When you hear about the subject of internal parasites, the most common worm that comes to mind are heartworms. Heartworms are nasty little creatures that can prove to be fatal if left unchecked. However, there are other parasites to look out for which are equally dangerous to your dog or puppy.

Roundworms: Roundworms spend their time floating inside the liver, heart, and the lungs of your dog’s body. When they mature, they make their home inside the small intestines where they continually feed on the food that your dog eats. Signs that your dog may be infested with roundworms include gas, enormous surges in appetite, diarrhea, and bloating.

Whipworms: Whipworms can be found living inside the large intestine of your dog, which is where they also reproduce. Dogs can become infected with whipworms by eating the stools of other dogs that contain the parasite. Sometimes a dog can easily become infested with whipworms after stepping in dog feces when walking outside and then lick their paws. These little creatures can cause your dog to have diarrhea, bloody stools, dry fur, and an increase in appetite.
