Disease transmitted by mosquitoes. The insect injects a parasite that spreads through the bloodstream and will progressively weaken the animal. There is no cure or effective treatment. The only prevention is done by the use of collars that have a repellent effect on the mosquito.
The manifestations are varied: slimming, long nails, blood loss from the nose, wounds and injuries in the organs.

Parvovirus, Distemper, Hepatitis and Leptospirosis
Are highly contagious viral diseases, affecting more frequently young animals. Have a high degree of mortality and vaccination is the only way to avoid contagion.
For the dogs that are being adequately protected and their owners reassured, there is a vaccine program that consists in successive reinforcements for major of diseases until the dog's immune system is able to tackle the agents involved.

Disease transmitted by mosquitoes. This animal bites and injects a parasite that enters in the bloodstream, causing severe damage to the heart. There is treatment, but sometimes the damage is already irreversible. There is a monthly prevention of disease through a pill.

Roundworms or Nematodes
The Nematodes are worms with a cylindrical body with two ends pointed, the mouth and anus. There is sexual dimorphism (differentiation), males are usually smaller than females. Their length varies according to species, between one millimeter and one meter.
The development cycle is almost always direct, requiring no intermediate host. They put daily a large numbers of eggs, that are eliminated in the excrements of the dog, and after a few days, become weeds, either in the form of embryonated eggs, either in the form of larvae.
When they are ingested by a new host (another dog) and reach his intestines, the ingested larvae or hatched from fertilized eggs, invade the tissues and organs of the dog through the bloodstream and may even, in the case of pregnant bitches, infest the embryos.
The most common Nematodes in the dog are Toxocara Canis and Ancylostoma Caninum.

Tapeworms or Taenias
The Tapeworms have a flattened and long shape, are targeted, and in each segment (Proglottids) coexist male sexual organs and female (Hermaphrodite). Their size can vary from a few millimeters to several meters. The development cycle is almost always indirect, requiring one or more intermediate hosts.
The Proglottids mature, full of eggs with larvae, are shed and are eliminated with the excrements of the dog.
When the intermediate host, an insect (eg. the flea), eat the capsules with eggs, the larvae that are inside the eggs hatch, enter the bloodstream of the intermediate host, invade their tissues, and lodge in the form of Cysts containing Cystic larvae in their target organs.
When the dog ingests the infested intermediate host, or part of it, in his digestive pipe gives up the hatching of Cysts containing Cystic larvae, and the head of the Cestoda attaches to the intestinal mucosa of the dog, pursuing their development until convert into adult parasite.
The Cestoda more common in dogs is Dipylidium Caninum and his intermediate host is the flea.
The dogs should be dewormed for the first time against Nematodes from the fifteen days, and should have successive deworming every two weeks, until reaching the age of two months, the time from which they should be dewormed against Tapeworm.
Adult dogs should be dewormed, 6 in 6 months against both types of parasites, but if they live in highly contaminated areas, and in contact with other animals should be dewormed 3 in 3 months.
They are some worming acts only against Roundworms, others only against Tapeworms, and others against the two types of parasites. Consult your veterinarian on how often and what products should dewormed your dog.

This disease causes changes in the articulation of the femur in large breeds, causing pain and difficulty in locomotion.
It is a multi-factorial disease, and it may be congenital or acquired by dietary changes, excessive exercise, among others.
It is important to make a radiographic diagnosis at the 8 months of age, to have a first notion of whether or not the pathology.

Fleas cause in most animals severe allergic reactions (caused by the flea saliva) in which they start biting and scratching areas attacked, leaving the hair with a bad state. By eating the fleas, not only the animal but also children can become infected with roundworms, once the flea lodge these parasites.
Sometimes, the fleas bite us, creating reactions of itching. Effective supervision should be done monthly or through an injection of 6 in 6 months.

Ticks can cause severe fevers, may even cause death to animals and people, and they are simply snapped a few hours.
Effective supervision should be done at least in the warmer months of the year. Prevention is also made with vaccination in December / January or July / August.
