Dogs + Parasites

  • Owning a puppy can be an extremely rewarding experience but it is also a large responsibility that lasts the entire lifetime of the dog. Working with your veterinarian, there are several preventive measures to help keep your puppy safe and healthy as he grows up, including vaccination, parasite treatment and prevention, identification, and spaying or neutering your dog.

  • Rocky Mountain Spotted Fever (RMSF) is spread by various species of ticks and is not confined just to the Rocky Mountain regions of North America. Clinical signs can be non-specific and affect multiple body systems. Early diagnosis and treatment give the best prognosis for recovery after treatment with antibiotics. Prevention of tick bites and prompt removal of ticks is important.

  • Roundworms (nematodes or ascarids) are parasites that live freely in the intestine, feeding off of partially digested intestinal contents.

  • Salmon poisoning is caused by a type of bacteria found within parasitic flatworms that infect the tissues of wild fish found in coastal streams of the Pacific Northwest.

  • Sarolaner is given by mouth and is used to treat flea and tick infestations and has also been used off-label to treat certain types of mange and mites. Give as directed. Side effects are uncommon but may include stomach upset or neurologic symptoms. Do not use in pets with a history of seizures. If a negative reaction occurs, please call the veterinary office.

  • Tapeworms are flat intestinal worms that are made up of many small segments, each about ¼ – ½" (3-5 mm) long. Unlike roundworms that live freely in the intestinal tract, tapeworms attach to the wall of the small intestine using hook-like mouthparts.

  • Heartworm disease is caused by a parasite called Dirofilaria immitis, better known as heartworm. Dogs become infected when they are bitten by an infected mosquito that is carrying immature heartworms. This handout discusses signs, diagnostic tests, treatment, and prevention in dogs.

  • Ticks are parasites that feed on the blood of their host and can in turn transmit diseases to your pets or even you. They are prolific breeders, and their life cycles can extend through multiple seasons. Prompt removal or use of preventatives limit or prevent the spread of disease or kill the ticks.

  • Von Willebrand's disease causes an inability for blood to clot resulting in excessive bleeding. If this disease is suspected, initial screening tests include a complete blood count (CBC), buccal mucosal bleeding time, and a coagulation profile. More advanced diagnostics include assays that assess the quantity and functionality of vWF. DNA testing is available and most commonly used to evaluate animals used in breeding programs.

  • Whipworms are intestinal parasites that cause bloody diarrhea. They are diagnosed by finding eggs on microscopic examination of the stool. These eggs, however, are difficult to find. Several medications are effective against whipworms. All medications must be repeated monthly for three months to clear the infection.
