Factors to Consider When Choosing Treatment


Your pets lifestyle is a strong determinant of their risk for getting fleas, ticks or other parasites. If they spend a lot of time outdoors, time around other pets or time in tall grass or wooded areas , their risk is much higher. But if you have an indoor cat, or an un-adventurous chihuahua, then it is less likely they will contract a parasite.

Risk Tolerance

Pet-parents should consider the risk they are willing to absorb. With below zero temperatures from November to February in Canada, the odds of contracting a parasite go down, but do not go to zero. Some pet-parents prefer to focus prevention some parasites more than others too, depending on their specific circumstances.


The price of medication and treatments highly vary based on your pet’s size and level of need. It’s recommended to budget a few hundred dollars per year if you are looking for the top of the line options. None of these treatments are mandatory, but consider your options with a professional to determine what you can manage.
