Parasites

  • Feline miliary dermatitis is a skin condition that typically results from an underlying allergic reaction, most commonly to fleabites. An affected cat will have a very itchy rash and may lick, bite, and scratch at the affected skin, quickly progressing to small lesions with scabs on them. The offending allergen must be removed for long-term resolution.

  • Mites and lice can cause trouble for guinea pigs. Some mites may cause no clinical signs, while others can cause extreme signs, including itchiness, crusty skin, hair loss, and secondary bacterial skin infection. This article summarizes diagnosis and treatment.

  • Mites affecting pet hedgehogs, often called quill mites, are fairly common. Initially, an affected hedgehog may become itchy but if mites are left untreated, the clinical signs can become severe. Treatment for your hedgehog should always be under the guidance of a veterinarian.

  • Moxidectin and fluralaner are combined in one topical treatment for use in cats. Moxidectin topical is an avermectin antiparasitic that is used to prevent heartworms and treat intestinal parasites (hookworms and roundworms). Fluralaner is used to treat and prevent fleas and also kills black-legged ticks (deer ticks). Give as directed. Side effects are uncommon but may include hair loss at the application site, itching, vomiting, diarrhea, lethargy, excessive drooling, and dry skin. Moxidectin + fluralaner should not be used in pets that are hypersensitive or allergic to it. Do not use this medication in sick, debilitated, or underweight cats. Use caution in cats with known neurologic disorders. If you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately. If they are not available, follow their directions in contacting an emergency facility.

  • Moxidectin is an avermectin antiparasitic that is used to prevent heartworms and treat intestinal parasites. Imidacloprid treats and prevents fleas. These two drugs are combined in one topical product for use in cats, dogs, and ferrets. Use as directed. Side effects are uncommon and usually short-lived, however, if you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately.

  • Moxidectin + sarolaner + pyrantel is a heartworm disease preventive for dogs that also treats and prevents internal parasites (hookworms and roundworms) and kills fleas and ticks. This medication is given by mouth as a flavored chew tablet. At regular doses, this medication is well-tolerated. Your veterinarian will advise you on the safety of moxidectin + sarolaner + pyrantel use in your dog. If you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately.

  • Parasites are not commonly diagnosed in pet birds; however, when present, they can cause generalized debilitation. With external parasites, your veterinarian can often make a diagnosis based on a physical examination and a microscopic analysis of skin lesions. Intestinal parasites are usually discovered when the feces are examined microscopically. Blood parasites are typically found during a routine blood count. All anti-parasite treatment should be under the advice of your veterinarian.

  • The common rabbit pinworm, Passalurus ambiguus, is an intestinal parasite. It does not posea serious health threat to rabbits, but it can cause uncomfortable itching and skin inflammation or redness around the anus. Rabbits become infected with pinworms by eating feces that contain pinworm eggs. Pinworms are challenging to treat because rabbits are coprophagic, so can potentially reinfect themselves during treatment.

  • The most common conditions affecting pet prairie dogs are: obesity, dental problems, cardiac disease and intestinal parasites. Regular scheduled veterinary examinations will be of great benefit to help discover problems or diseases before they cause a critical illness.

  • The American Animal Hospital Association and American Veterinary Medical Association have established guidelines to standardize preventive health care for cats, helping them to live longer, healthier lives. This handout provides an overview of the recommendations within these guidelines and why they are so important.
