Dog Endoparasites (intestinal worms)
If you really consider yourself a true friend of
Nematodes, which are as long and thick as a pen refill, are easy to recognize. Both their extremities are pointed and they are a yellowish white color. The worm disease begins when a young female dog becomes infested with nematodes. These eggs are resistant to dryness, but also to disinfectants, which makes it difficult, if not impossible, to eliminate them from a pound. They develop into little larvae which can also encapsulate themselves.
As soon as a female dog enters in heat, part of the larvae enter the blood flow and reach the intestine passing through the liver and lungs, producing worms again; nevertheless, there hasn't been any external infestation. The puppies are contagious by the pregnant animal, which is why it is also possible to find worms in them one or two weeks after birth.
The adult nematodes from the intestine need to be eliminated in the usual way.
