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.

  • Ringworm infections in cats are caused by a fungus, not a worm. They can be easily recognized, though definitive testing by fungal culture is recommended. Ringworm is highly contagious and can be spread between animals and from animals to people. The clinical signs, diagnosis, treatment, and risks are explained in this handout.

  • 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 are one of the most common intestinal parasites observed in cats. Almost all cats will become infected with roundworms at some point in their life, most often as kittens. Roundworms are not particularly harmful to adult cats, but large numbers may cause life-threatening problems in kittens and debilitated older cats. Roundworms can also be transmitted to humans. Diagnostic testing, treatment, and preventive measures are explained in this handout.

  • Roundworms are the most common gastrointestinal worm found in dogs and can also be transmitted to people. They are of most concern to puppies when present in large numbers, causing stunted growth, a pot-bellied appearance, and recurrent diarrhea. Diagnostic testing, treatment, and preventive measures are explained in this handout.

  • 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.

  • Sarcoptic mange, also known as scabies, is caused by a parasitic mite that burrows just beneath the surface of the skin. The presence of the sarcoptic mite causes intense itching; an affected dog will constantly chew and scratch his skin. Sarcoptic mange is highly contagious to other dogs and humans.

  • 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.

  • Selamectin + sarolaner is used topically on the skin to treat various parasites, both on and off-label, and prevent heartworm in cats. Side effects are rare but may include hair loss at the application site, gastrointestinal upset, skin reactions, or neurologic signs. It should be used with caution in sick or underweight cats. If a negative reaction occurs, please call your veterinary office.

  • Tapeworms are parasites that infect the gastrointestinal tract of cats, other animals, and humans. Several types of tapeworms are known to infect pets, but the most common species observed in cats is Dipylidium caninum, which is transmitted through fleas. Risk factors, clinical signs, treatment, and prevention are explained in this handout. Other, less common types of tapeworms that affect cats and humans are also covered.
