Parasite Detection & Prevention


At Hillside it is our priority to ensure the health and safety of you and your family.

We live so closely with our sweet pets – we kiss and cuddle them, sleep with them, play in the yard with them. Some common parasites can be transmitted from our pets to us, sometimes causing serious illness, especially in children. That’s why we strongly believe that parasite detection and prevention is essential to your pet’s health – and the health of you and your family.

There are a number of parasites that affect our pets:

  • Fleas - Fleas cause itching, hair loss, and can sometimes transmit disease (such as Borelliosis andTapeworms) to pets and people. Even indoor cats can get fleas, becuase they can be carried in on people's clothes.
  • Ticks - There are many types of ticks and they carry diseases like Lyme disease, Ehlrichiosis, and Anaplasmosis. Ticks are becoming much more common because of the warmer winters, and they like any long grass, including people's back yards! We recommend a medication for tick prevention (Bravecto) for months when the temperature is above 4 degress celsius.
  • Heartworm - Spread by mosquitos, this parasite lives in the heart and lungs, and over time causes heart disease and lung disease. While not very common in Ontario, the number of cases is increasing. We recommend a monthly preventative medication (Heartgard or Revolution) during the summer, and annual blood testing.
  • Intestinal Worms - intestinal worms are picked up from infected feces and grass, and your pets can be exposed when outside for a walk. They can also be transmitted to puppies and kittens from their mothers, which is why we usually deworm all young pets.  They can cause anemia, bloody stool, and weight loss in pets. Roundworm can be spread to people, especially children, causing fever, malaise, and travel to places like the liver, heart, nervous sytem, or eyes! Regular fecal testing can detect the eggs of these worms that are too small for the human eye to see.  Our heartworm medications often control intestinal parasites also.
  • There are a few skin mites that can cause itching and hair loss. If your pet is experiencing this, we may do a skin scraping, or a trial of medication to help diagnose this.
