Parasite Prevention Request

Fleas, Ticks, Heartworms & Intestinal Worms

Parasites are now a year-round problem for cats and dogs. Read on for details, our recommendations, pricing, and our online order form, and click here for more information about the main types of parasites that affect our pets.

The safest option is to treat your pet every month. Fleas are a problem year-round, with their numbers increasing over the spring and summer, and becoming worst in the fall. Ticks particularly love spring and fall, but they become active whenever the temperature rises above freezing – and this past winter for the first time ever, Toronto’s AVERAGE winter temperature was above zero degrees! Heartworm is spread by mosquitos, and prevention is essential from late spring until early winter. Intestinal worms can be spread year-round by contact with other animals or their feces, contaminated dirt, or if your pet eats infected prey like rodents or bugs.

If you prefer not to use prevention year-round, the most active parasite season is March to November. Make sure that you treat every pet in your house, even if they don’t all go outside – many parasites can hitchhike inside on shoes or other pets! In particular, if you only treat some of your pets, new fleas carried inside can avoid treatment by taking refuge on the untreated pet(s) and quickly reproduce, making infestations impossible to eliminate.

If you have questions about our recommended medications, please give us a call at 416-537-9677.

If your cat has had a full exam with one of our veterinarians within the last 12 months, you can go ahead and request their prevention by submitting the form below. If they haven’t been seen within 12 months, or if you have any other preventative care or health concerns you would like to address at the same time, please give us a call at 416-537-9677 to book an appointment.

Recommended Preventative Medication for Cats: NexGard Combo, a topical medication applied to the back of your cat’s neck, protecting against fleas, ticks, ear mites, roundworms, hookworms, heartworms, and ALSO tapeworms.

Weighing yourself while holding your pet is a good technique if your pet is too big to stand on a small household scale. If you are unable to weigh your pets at home, just write 'no scale'. However, if we do need an updated weight in order to dispense medication (i.e. if your pet is a growing puppy or their last recorded weight was right between two weight categories), they will need to come in to the clinic for a quick no-charge weight check.

How many doses of medication do you want to order for each pet?*
To order whichever medication our veterinarians recommend, please choose the number of doses you would like to order below. Nexgard Combo is our recommendation for most cats. Nexgard Spectra is our recommendation for most dogs.
