Parasites in Dogs and Cats: Be Very Careful!


Whether internal or external, more or less dangerous, parasites in dogs and cats is an issue that we cannot ignore.

It is that they not only affect our pets. They can transmit diseases to humans, particularly young children.

Deworm first

When a new four-legged member arrives in the family, among many other things we should consider, is his deworming. For this reason, the visit to the veterinarian should not be delayed.

Fleas, ticks and intestinal worms can infect not only our pets but their environment, including ourselves.

Consult a professional about the best method and the appropriate frequency to deworm your pet. Find out about the correct way to take care of the home environment of these annoying visitors.

Currently, there are broad-spectrum pipettes that are effective in controlling both internal and external parasites. Due to its easy application, animals – especially cats – are not stressed as much as with the anti parasitic drugs given by mouth.


Most internal parasites are roundworms (worms), flatworms (tapeworms) and single-celled organisms such as coccidia and giardias.

Dogs and cats can defend themselves with more or fewer weapons from them, depending on the degree of the infestation, their general state of health and the variety of these specimens that populate their intestines.

For this reason, the same disease transmitted by these unwelcome beings can be mild, moderate or severe. The best thing will be, then, not to underestimate the endoparasites and keep our pets free of them.


Fleas, ticks and scabies mites are the most common external parasites that may have a bad time bringing your puppy or your pussy.

Flea and tick bites, in addition to causing dermatitis, can lead to severe allergies. They are also likely to bite you or your family. Do not forget this detail.

Fleas also function as vectors for tapeworm, which develops the part of its cycle within them. Therefore, the best way to prevent your pet from having this intestinal worm is to keep it free of fleas.

Signs of parasites in dogs and cats

Some signs that your pet has intestinal parasites can be:

  • Pale tongue
  • Noises in the belly
  • Soft stools
  • Slimming

On the other hand, the presence of external parasites can cause :

  • Loss of hair
  • Bad smell
  • Injuries caused by scratching

Worm infection in humans

The intestinal worm can also affect humans who are in contact with affected pets.

Most of the time, the contagion is produced by the accidental intake of the larva, which can also penetrate through the skin.

Children are at a higher risk of becoming infected, especially if they play in areas that are contaminated with feces.

If the larvae reach the organs or other tissues they can cause damage to the lung, brain or liver and even blindness if they migrate to the eyes.

How to avoid worm infestations in people

With proper hygiene practices, worms should not be a problem for us. Consider the following details:

  • Prevent children from swallowing land while playing.
  • Clean your hands after touching the ground and being in contact with pets.
  • Do not walk barefoot outside, to protect the feet of larvae that can be found in the environment.
  • Thoroughly wash the vegetables that are to be consumed raw.
  • Immediately collect fecal matter from your pet, both from public areas and from inside your home.
  • Keep your cat inside the house.
  • Clean and ventilate the place your pet has for rest every day.

Prevention is the key

The best way for parasites in dogs and cats not to become a nuisance or a serious problem, both for them and for us, is prevention.

Deworming, both internally and externally to pets and in the manner and times indicated by the veterinarian, is essential so that our animals are healthy and do not transmit diseases to humans.

Remember that this is also a good way to show your hairy how much you love them.
