Deworming should be done every three month. If you choose a product which covers flea and worms like Trifexis then you must give monthly.  If not on an intestinal parasite combination product, have a fecal test performed 2-4 times per year and treat appropriately.

Deworming Adult Cats

Treatment should be given every 3 months. Deworming is most important in hunter and outdoor cats may require more frequent monthly worming.

Why is Deworming Important in Puppies and Kittens?

Toxocara canis and Toxascarisleonina are two important species of roundworms in dogs. Toxocara canis causes more significant disease and also may be transmitted to humans.Toxocara (roundworms) are present in puppies from 2 weeks olds and in kittens from 6 weeks old because they get from mother through placenta and milk. Almost all young animals are infected and Toxocara can cause serious disease. Toxocara can also cause disease in humans if the worms are ingested. This is especially important in children as it can cause blindness.

Why is my Pet at a Higher Risk if they have Fleas?

When animals have fleas they can be accidentally ingested whilst grooming due to flea irritation. Flea larvae can feed on the eggs of the tapeworm  found in the environment and develop within the abdomen of the flea. If an infected flea is ingested the tapeworm also enters the dog or cat. The scolex of the tapeworm attaches to the intestinal mucosa of the host and grows into an adult tapeworm. Rarely this can also happen to humans, especially children, if fleas are ingested. This is why it is important to have both good flea and worm control.

Intestinal Worms: The Facts

It is important to ensure that your pet is dewormed at regular intervals, a large worm burdens can accumulate quickly and can pose a serious health risk to your dog or cat. There are many types of worms that infect dogs and cats some infections left untreated can even be fatal in young puppies.

Younger animals are more susceptible to worm burdens as their immune system is less developed, and in general, they are at higher exposure than adults. However this doesn’t mean that you shouldn’t have your adult dog or cat checked and treated regularly for intestinal parasites.

Some worms are easily identified in the stool or vomit without the use of specialized equipment though some need to be identified by the vet using a microscope in the laboratory. Bring in a fecal sample to your next visit to have it evaluated for parasites.

Signs of Worms

Some types of worms will not show any signs of infestation until in the later stages, such as in a pregnant female dog or times of environmental stress where roundworms activate multiply. These infections then can result in the infection of others around them and any puppies that nurse from their mothers.

  • Common signs of worms can include:
  • Anemia (pale skin and gums)
  • Vomiting
  • Weight loss
  • Pot-belly (mostly in pups)
  • Bloody stool
  • Diarrhea
  • Dry/dull coat
  • General poor appearance
  • Weakness
  • Tail skidding (dog rubs butt on the carpet) sometimes it could be due to anal gland issue also.
  • Visible signs of worms or worm segments in stool, vomit, or around the anus dried in the fur

Again, the most important for treating intestinal worms is preventing it. You can take simple steps to preventing your puppy or dog from contracting an intestinal parasite.
