Parasites (worms)
***********************
Parasites are living beings such as worms or insects that live on or inside your pet. They usually feed upon your pet, which can cause them to be uncomfortable, malnourished or even die.
Intestinal Parasites
intestinal parasires, such as whipworms, hookworms, tapeworms, and giardia, are a very common problem in dogs. If your dog has exposure to other animals or is recently from a animal shelter , he or she is at higher risk.
Symptoms
Symptoms of intestinal parasites include vomiting and diarrhes, poor condition of fur, and in extreme cases DEATH.
However, some dogs with parasites do not show thes symptoms.
JUST BECAUSE YOU DONT SEE THEM DONT MEAN THAT THEY ARE NOT THERE.
It is more inportant to realize these worms live in the intestines, so you will not see them in the stool of your dog unless they are dead or dying.
