For some people, nothing is more rewarding than raising a dog. Unfortunately, dogs are prone to parasites, both externally and internally. External parasites suck blood and can cause infections and other problems. Internal parasites, or worms, can sometimes be deadly.

Fleas
-
Fleas are common external parasites that suck blood from your dog. They usually spread from dog to dog in an outdoor environment. Flea collars, shampoos and sprays are available at most pet stores.
Ticks
-
Ticks are an outdoor parasite that burrow into the skin of your dog and spread diseases. Pull them out of your dog's skin directly or kill them with topical sprays or shampoos. They thrive in long grass, so keep any lawn carefully mowed.
Worms
-
There are many kinds of internal worms that affect dogs. These worms can clog up the digestive system and sometimes even end up in the lungs. Give your dog a monthly de-worming pill to avoid these parasites.
Ear Mites
-
Ear mites generally reside in the ear canal, though they can live anywhere on the body. They spread quickly from animal to animal. They cause severe itching and even hearing damage. Special ear mite medicines should be applied directly to the ear canal.
Lice
-
Lice are blood sucking insects that must be transmitted by direct touch. They cannot survive in the environment. They are not transmittable to humans, as lice species prefer a specific host. Lice are easily treated by lice sprays.
