Our beloved pets are likely to get affected by external parasites and insect bites when exposed to outdoors such as dense and wooden vegetation or indoors where fleas can reside like carpet fibers and under furniture. The transmission of pests can also occur via other pets.

In order to prevent parasitic diseases in dogs it’s crucial to acknowledge the different types of diseases so you can have better understanding for its treatment and prevention.

Flea’s ability to spread diseases

Dogs and cats are constantly being parasitized by fleas. A little intestinal worm called Dipylidium caninum can infect your pets when they consume fleas that are bothering them. Cat’s scratch disease which is also known as bartonellosis, is an infection that can occasionally be acquired by individuals who have been scratched and is caused by a bacterium that is spread by fleas. Your dog may experience the following symptoms as a result of flea bites:

  • Intense skin discomfort and irritation that is present in areas other than the bites themselves.
  • losing hair
  • Skin maladies

Tapeworms spread by fleas

Dogs can sometimes swallow fleas while they are biting at irritated skin from flea bites or from licking or grooming their fur. If any of these ingested fleas have been infected with tapeworms, there is a possibility that your dog can get infected as well. Once within the digestive tract, the tapeworms will attach to the intestinal lining. If your dog has been infected with tapeworms, you can usually see worms or some other pieces near your dog’s back.


Sandfly-transmitted diseases

Small flying insects are called sandflies. They have the ability to spread the leishmaniasis agent to people, dogs, and, much less frequently, cats. Although this illness is common in the Mediterranean region, it is spreading northward.

Some pets experience a silent infection, showing no symptoms or warning signs. Clinical signs of infection appear as b. The size and form of the sores can change over time. Initially appearing as bumps or nodule lumps, the sores may develop into skin ulcers that may be covered by scabs or crust. The sores can be irritating even though they rarely hurt. Some individuals have enlarged glands close to the lesions present under the arm if the sores are on the arm or hand.


Illnesses spread by mosquitoes

Heartworm illness, a condition brought on by worms that settle under the skin, can be transmitted by mosquitoes in the south-east of France. Some worms can get stuck in the heart’s blood arteries and impair heart function.

The symptoms that dogs may experience range from a mild cough to complete heart failure. There can sometimes be no symptoms too. Cats usually carry a lot less worms, but they are more susceptible to the larvae. The larvae can cause an asthma-like strong inflammatory reaction in your pet.

Respiratory diseases can sometimes be fatal due to inflammation. Heartworm disease is very painful and it is not pocket friendly to treat once it has been contracted by your pet. In a dogs’ case, a single worm injection that is administered many times over the time of a month will get rid of adult heartworms. There is no particular treatment available for cats yet, only some supportive care can be given.
