Endoparasites (Intestinal Worms)

If you love your dog it will not be distasteful to watch, once in a while, his feces. It's very frequent to find the presence of intestinal worms.

Nematodes or cylindrical worms: Nematodes, with a length and thickness similar to a pen's lead, are easy to recognize. Both extremes end in points, and have a white yellow color. Worms affection starts with the infestation of nematode's eggs in a young female dog. These eggs resist dryness, but also disinfectants, so is almost impossible to eliminate them at a pound. They evolve in larvae that can also encapsulate.

As soon as a female enters her heat period, part of the larvae immigrates to the sanguineous torrent, and reaches the intestine passing through the liver and lungs, producing new worms; however, no new infestation has taken place from outside! The puppies are infected by the pregnant mother, so you will probably find worms also in them, one or two weeks after delivery. Adult nematods at the dog's intestine have to be eliminated by usual methods.

Taenia: Worms are a problem of young dogs and their mothers. On the contrary, taenias are found normally in adult animals. You can start suspecting of taenias if your dog suddenly gets thin and/or drags the back part of his body, sliding over it. You can only be sure if you find taenia's mature segments in his feces. Taenia has a small limaco aspect, move slowly and are angular, if carefully watched. To proof their presence is not as simple as that of the cylindric worms. Infestation is produced through infected fleas.
