Animal Hospital information on Heartworm, Ticks and Fleas

 Animal Hospital

Heartworm and Ticks and Fleas, Oh my!

Disease prevention

Along with the warmer weather come some of our spring health concerns. Among these are Heartworm disease, Fleas and Lyme disease from Ticks

Heartworm   is a blood parasite that is transmitted by mosquitoes. Both dogs and cats are at risk of infection.  Depending on your pet’s lifestyle, heartworm testing may be required to ensure that infection has not occurred. A monthly dose of an appropriate preventative is recommended to keep your pet safe. These prevention medications are given from June 1st to November 1st if your pet stays in this area. Heartworm testing is recommended every other year if your pet has been on prevention. When doing a heartworm test it’s also a good opportunity to do regular wellness preventive blood and urine screening.

Fleas are common during our warm weather months.  They are prolific breeders and can cause house infestations and transmit tapeworm parasites. With the change in our environmental temperatures, we are recommending prevention to start April 1st through till November 1st.

 Ticks have arrived in Ontario, each year expanding their area and growing in numbers. With  this increase comes the concern of tick borne diseases including Lyme disease, Canineanaplasmosis and Canine ehrlichiosis. We are therefore recommending a more thorough tick prevention program for our patients. There is now a much improved oral tick preventionmedication available which we recommend using monthly April 1st through to November 1st  For more information about Lyme Disease and Ticks visit the worms and germs website,

Please call the clinic for further information on appropriate preventative medications for your pet, or visit our website for additional information on these parasites. If you have already picked up your medications have a happy spring and summer!

What is Preventive and Senior Screening?

Did you know that dogs and cats age much faster than humans? That means that your pet’s annual exam is roughly equivalent to us seeing our own doctor every 5 to 7 years! Just like human doctors run periodic blood, urine and monitoring tests on us, the same is recommended for our pets. Our goal is to identify changes early, before our friends become sick.

Preventive Wellness Screens

Wellness screens are blood and urine tests designed for dogs and cats under seven years of age. Looking for early changes in liver, kidney, endocrine (thyroid and diabetes) and blood cell functions, these tests can be tailored to screen for overall health and breed-specific problems. This test can be run with heartworm testing or at your pet’s annual health exam.

Senior Screens

Senior screens are more in-depth screens which are tailored to the individual pet and owner. These may include blood testing, urine testing, blood pressure and eye testing. Given that our pets age rapidly, screening is aimed at slowing down degenerative processes and keeping our seniors comfortable for as long as possible.

Infectious Disease and Vaccine Update

Southern Ontario is experiencing an increase in rabies (dogs and cats) and leptospirosis (dogs). These can both be deadly infections and vaccines are available and recommended. Humans can also be affected.


Rabies is caused by a virus and transmitted through infected saliva via a bite or open sore. It affects humans, cats, dogs, skunks, foxes, coyotes, and now raccoons. Southern Ontario has had over 60 cases of raccoon rabies in the last year. Rabies vaccine for cats and dogs is a legal requirement in Ontario to help prevent spread and keep all of us safe.


Leptospirosis is a bacterial infection of dogs spread in the urine of wildlife, most commonly raccoons. The number of cases in our area has increased significantly in the last year. We are seeing cases in small and large dogs, notably dogs that have never left their backyards. Raccoons and other animals visit backyards during the night in search of food and commonly urinate and contaminate our lawns and gardens. Leptospirosis can cause acute kidney and liver failure in dogs and can also cause a flu-like illness in people. Yearly vaccination is recommended.
